摘要: Massive MIMO is a promising approach in order to increase the data rate of cellular systems while reducing their power consumption. While concept elegant, many potential show-stoppers have be investigated, make sure that idea keeps its promises. On such element claim massive can operate with very low digital signal processing accuracy, and hence reduced implementation complexity In this paper, we investigate impact quantization at resolution. Simulations show system correctly as few 2 or 3 bits resolution end chain, limiting degradation 1 dB required signal-to-noise ratio.
