In this paper, we analyze the effect of time-varying channels on the performance of a non-coherent massive single-input multiple-output (SIMO) uplink system based on M-ary Differential Phase Shift Keying (M-DPSK), when amalgamated with bit-interleaved coded modulation relying on iterative decoding (BICM-ID). Additionally, we study the number of receive antennas (R) required in hostile time-varying channels for attaining a similar performance to that achieved for stationary channels. Furthermore, we analyze the maximum achievable rate (MAR) in conjunction with the specific modulation and coding schemes considered. The analysis is based on extrinsicinformation transfer (EXIT) charts parametrized by R, which varies with the signal to interference-plus-noise ratio (SINR). Our numerical results show that the system is robust to the effects of the channel’s temporal correlation and that the simulation-based MAR closely matches the semi-analytical achievable rate obtained using EXIT charts. Hence, our system can be applied to scenarios associated with the short coherence time of high-speed railway systems, for example.
