Bit Error Rate Performance Comparison of Large Scale MIMO Receivers using Spatial Modulation

This paper proposes a novel approach of an Approximate Message Passing (AMP) detection method for Large Scale Multiple Input Multiple Output (LS-MIMO) receiver which uses M_T transmit antennas and M_R receive antennas to detect the information bits transmitted. An efficient transmission technique called Spatial Modulation (SM) in which the information bits are encoded and conveyed through the indexes of the transmit antennas using M-ary Amplitude and Phase Shift Keying (APSK) modulation to increase the efficiency of the receiver. Simulation results show that the Bit Error Rate (BER) performance of the proposed detection method performs near to the Maximum Likelihood (ML) detection and outperforms than the Modified Maximum Ratio Combiner (MMRC) detection.
