Description
Summary:In this paper, the performance of uplink multiuser massive multiple-input multiple-output (MIMO) system with spatial modulation over transmit-correlated Rayleigh fading channel is investigated, where a large number of antennas are deployed at the base station and linear zero-forcing (ZF) receiveris employed for detection. By taking the transmit correlation and the randomness of shadow fading in to account, the bit error rate (BER) performance of the system is analyzed. According to the performance analysis, an approximated expression of overall average BER of the system is attained. Besides, asymptotic performance is studied and the corresponding BER expression at high signal-to-noise ratio is derived. On this basis, the diversity gain of the system can be obtained for performance evaluation. Simulation results show that the derived theoretical expressions matchthe simulated values well, which verifies the correctness of our analysis.
