Title: Reduced-complexity partial interference cancellation receiver in spatial modulation aided zero-padded single carrier transmission
Abstract: In this paper, the partial interference cancellation receiver with successive interference cancellation (PIC-R-SIC) in the spatial modulation (SM) aided zero-padded single-carrier transmission is studied, and two complexity reduction methods are presented by employing the Toeplitz structure of the channel matrix. Specifically, a shorten PIC-R-SIC (S-PIC-R-SIC) is first proposed, where, for each symbol detection, the equivalent channel matrix size is reduced. This method has much lower complexity than the conventional PIC-R-SIC with a cost of performance degradation. Next, the combining of S-PIC-R-SIC with M-algorithm is considered to improve the performance. Simulation results shown that the combined method can achieve better performance while lower complexity than the conventional PIC-R-SIC.
