    Direct experimental verification of shot noise in short channel MOS transistors2005In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 41, no 15, p. 869-871Article in journal (Refereed)
    Abstract [en]

    Drain noise current was measured at an extended temperature range on n-MOS transistors of various lengths made in a 0.18 urn process. A comparison with theoretical noise models strongly indicates the mechanism of shot noise produced near the source by diffusion currents, as proposed by Obrecht et al. © IEE 2005.

    Organic laser based on lithographically defined photonic-bandgap resonators1998In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 34, no 1, p. 90-91Article in journal (Refereed)
    Abstract [en]

    The authors report the fabrication and characteristics of organic solid-state waveguide lasers with feedback from a photolithographically defined rhomboid photonic bandgap lattice. The lattice is formed by etching holes of depth 10-40 nm in SiO2 and filling them with the organic gain medium. The gain medium is part of a planar waveguide formed by air/organic layer/SiO2.

    Energy-Efficient Data Representation in LDPC Decoders2006In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 42, no 18, p. 1051-1052Article in journal (Refereed)
    Abstract [en]

    Data representations for LDPC decoders using the sum-product algorithm in the log-likelihood domain are considered. It is suggested that the look-up table implementation of the domain transform function is separated into two parts, allowing a compact representation of the internal state data. Memories and bus widths can be reduced by typically 16\%, while the imposed hardware overhead is insignificant.

    Characterization of Electromagnetic Properties in Iron-Mine Production Tunnels2012In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 48, no 2, p. 62-63Article in journal (Refereed)
    Abstract [en]

    Modern underground mines require reliable wireless communication for transmitting voice data, operating surveillance cameras, and monitoring mining equipment such as heavy vehicles. The electromagnetic characteristics of mines therefore have to be considered when determining the type of wireless technology for such critical applications. In this reported work, measurements of radio interference levels, path loss, and multipath propagation are performed in the world's now largest iron ore mine, situated in Sweden, to determine a suitable wireless technology for this mine.

    Continuous-flow variable-length memoryless linear regression architecture2013In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 49, no 24, p. 1567-1568Article in journal (Refereed)
    Abstract [en]

    A pipelined circuit to calculate linear regression is presented. The proposed circuit has the advantages that it can process a continuous flow of data, it does not need memory to store the input samples and supports variable length that can be reconfigured in run time. The circuit is efficient in area, as it consists of a small number of adders, multipliers and dividers. These features make it very suitable for real-time applications, as well as for calculating the linear regression of a large number of samples.

    Terminal antenna diversity characterisation using mode stirred chamber2001In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 37, no 5, p. 273-274Article in journal (Refereed)
    Abstract [en]

    Antenna diversity in mobile terminals is likely to be commonly used in future mobile communication systems. Methods for characterisation of antenna diversity performance are therefore of interest. Previous work has demonstrated diversity performance measurements in typical indoor and outdoor environments. A new characterisation method using a mode stirred chamber, with several advantages over existing techniques, is proposed.

    Printable rectifying device using Si-composite2008In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 44, no 1, p. 53-55Article in journal (Refereed)
    Abstract [en]

    The R&D in finding low-cost manufacturing of electronics and electronic components is intense. One research route is aiming at roll-to-roll printing of organic electronics but the typically low mobility in organic semiconductors results in fundamental difficulties to fabricate, e.g., diodes for operation at high frequencies. A novel diode has instead been realised by screen-printing a silicon-powder composite with the intention to utilise the high mobility and the high operation frequency potential of silicon. The current against voltage (I-V) characteristics of the printed device reveal diode behaviour but so far with a too high ideality factor and resistance to be practically useful. By optimising device geometry, composite, and printing process low-cost printed, high frequency diodes (MHz-some GHz) may be viable.

    Demodulation of space-time codes in the presence of interference2001In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 37, no 11, p. 697-698Article in journal (Refereed)
    Abstract [en]

    Two interesting space-time coding schemes for communication systems are the recently proposed differential space-time modulation (DSTM) scheme and the differential space-code modulation (DSCM) scheme. DSCM gives better performance than DSTM by exploiting the spatial degree-of-freedom to suppress interference. We show that, for DSCM, a maximum-likelihood (ML) demodulation approach, based on a deterministic channel model, improves the performance significantly compared to a previously proposed stochastic channel model based method.

    Suppressing phosphorus diffusion in germanium by carbon incorporation2005In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 41, no 24, p. 1354-1355Article in journal (Refereed)
    Abstract [en]

    A problem in the Ge MOSFET process is that the phosphor-us for n-type doping in Ge diffuses very fast. It is very difficult to form the shallow source/drain p-n junctions. It is reported, for the first time, that the phosphorus diffusion in Ge during activation (or annealing) can be suppressed effectively owing to carbon incorporation.

    RFI suppression in ultra-wideband SAR systems using LMS filters in frequency domain2001In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 37, no 4, p. 241-243Article in journal (Refereed)
    Abstract [en]

    A least-mean-square algorithm in the frequency domain, with amplitude normalisation. is proposed to remove narrowband radio frequency interference in low-frequency ultra-wideband synthetic aperture radar systems. The performance uf the algorithm was tested on experimental data acquired with the CARABAS system.

    Quasi-Maximum-Likelihood Multiple-Symbol Differential Detection for Time-Varying Rayleigh Fading Channel2009In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 45, no 22, p. 1127-1128Article in journal (Refereed)
    Abstract [en]

    The maximum-likelihood multiple-symbol differential detector (ML-MSDD) has better bit-error-rate performance than many other detectors for differential modulation. Unfortunately, the computational complexity of ML-MSDD quickly becomes prohibitive as the observation window size grows. While low-complexity MSDD algorithms for the time-invariant Rayleigh fading channel have been considered before, there is a need for low-complexity MSDD algorithms for general time-varying Rayleigh fading channels. A polynomial-time complexity approach called semi-definite relaxation (SDR) is employed to achieve differential detection with near maximum-likelihood (ML) performance. The proposed SDR quasi-maximum-likelihood (QML) multiple-symbol differential detection (SDR-QML-MSDD) is efficient in that its complexity is polynomial in the observation window size, even in the worst case, while it exhibits almost the same performance as ML-MSDD does.

    Optimal time allocation for RF-powered DF relay-assisted cooperative communication2016In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 52, no 14, p. 1274-1276Article in journal (Refereed)
    Abstract [en]

    A decode-and-forward (DF) relay-assisted RF-powered cooperative communication between an RF energy harvesting source and an information sink is considered. DF relay aids the communication between these two distant wireless nodes by (i) RF energy transfer to the source, and (ii) relaying source data to the sink. To enable efficient RF-powered delay-constrained information transfer to the sink under Rayleigh fading, joint global-optimal time allocations for information and energy transfer are derived. Impact of relay position on throughput and optimality of the analytical solutions are numerically investigated.

    CMOS on-chip clock for digital signal processors1993In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 15, no 8, p. 669-670Article in journal (Refereed)
    Abstract [en]

    An on-chip clock for frequencies up to 190 MHz is presented. This clock generator can be used for application specific digital signal processors which are clocked faster than the off-chip system clock. It is useful for both processors with a few cycles per sample or for high frequency bit-serial processors which need a large number of cycles.

    Unified architecture for 2, 3, 4, 5, and 7-point DFTs based on Winograd Fourier transform algorithm2013In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 49, no 5, p. 348-U60Article in journal (Refereed)
    Abstract [en]

    A unified hardware architecture that can be reconfigured to calculate 2, 3, 4, 5, or 7-point DFTs is presented. The architecture is based on the Winograd Fourier transform algorithm and the complexity is equal to a 7-point DFT in terms of adders/subtractors and multipliers plus only seven multiplexers introduced to enable reconfigurability. The processing element finds potential use in memory-based FFTs, where non-power-of-two sizes are required such as in DMB-T.

    Orthogonal space-time block coding with antenna selection and power allocation2003In: Electronics Letters, ISSN 0013-5194, E-ISSN 1350-911X, Vol. 39, no 4, p. 379-381Article in journal (Refereed)
    Abstract [en]

    A system that uses the Alamouti code on two out of three transmit antennas selected via feedback is studied. It is shown that in addition to optimal antenna selection, optimal power allocation can improve the performance with 1dB in uncorrelated Rayleigh fading. The impact of errors in the feedback link is also studied.
