Analysis of the performance of a non-coherent large scale SIMO system based on M-DPSK under Rician fading [pdf]Paper  doi  abstract   bibtex   
In this paper we extend the analysis of the performance of a non-coherent large-scale single input multiple output (LS-SIMO) uplink system based on M-DPSK to consider Rician-K fading channel conditions. The interference is analyzed for a generalized k-factor and we provide analytical expressions of the signal to interference plus noise ratio (SINR) for a single user. We demonstrate that for Rician fading our proposed system is independent of the channel statistics, which simplifies the receiver design. The performance is evaluated in terms of the required number of antennas and the error probability. Finally, we provide numerical results showing that our proposal require a lower number of receive antennas to achieve a given error probability than other non-coherent benchmark schemes available in the literature. As the results show an increase in the spectral efficiency using DPSK modulation combined with NC LS-SIMO, this makes it a good candidate for 5G and beyond.
