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 investi-gated, where a large number of antennas are deployed at the base station and linear zero-forcing (ZF) receiver is employed for detection. By taking the transmit cor-relation and the randomness of shadow fading in to ac-count, the bit error rate (BER) performance of the sys-tem is analyzed. According to the performance anal-ysis, an approximated expression of overall average BER of the system is attained. Besides, asymptotic performance is studied and the corresponding BER ex-pression at high signal-to-noise ratio is derived. On this basis, the diversity gain of the system can be ob-tained for performance evaluation. Simulation results show that the derived theoretical expressions match the simulated values well, which verifies the correct-ness of our analysis.
