Abstract [en]

A less complex and generic channel estimation algorithm for long term evolution (LTE) and digital video broadcasting-handheld (DVB-H) downlink standards, is proposed. The technique, here referred to as minimum mean square error sliding window (MSW) technique, obtains less computational complexity than previous mean squared error (MSE) algorithms [3] at the cost of some 0.3 dB less SNR. The computational complexity is decreased by a factor 3 for the LTE 5-MHz downlink case and by 30 for the DVB-H standard case. Simulated results in terms of mean squared error and bit error rates are presented for a quadrature phase-shift keying (QPSK) systems with interleaving and coding of the data. All simulations are done at the behaviolar-level level.
