Abstract [en]

The power consumption of analog-to-digital converters (ADCs) grows linearly in the number of antennas in massive MIMO base stations. To reduce power consumption, one-bit ADCs can be used. It is believed that the nonlinear distortion of onebit ADCs makes channel estimation and symbol equalization in such systems computationally complex and resource demanding. In this paper, it is shown that low-complexity linear channel estimation and symbol equalization are feasible in massive MIMO with one-bit ADCs when the number of channel taps is large. The effective SINR of the received symbol estimates of a maximum-ratio combiner with estimated channel state information is 4 dB lower in a system with one-bit ADCs than in an equivalent unquantized system.
