An iterative receiver in the frequency-domain (FD) for the single carrier multiple-input multiple-output (MIMO) system is proposed. The proposed iterative receiver, using turbo theory, jointly performs soft interference cancellation (SIC), frequency-domain (FD) decision feedback equalization (DFE) and the function of the SCTCM decoder. The proposed iterative receiver can obtain better performance by using soft information derived from the decoder to perform the SIC and update the coefficients of the forward filter and feedback filter of FD-DFE. Simulation results shown that the proposed iterative receiver can improve the system performance significantly compared with FD linear equalization (LE). Moreover, the performance of the proposed receiver using fractional rate sampling approaches the perfect detection with an ideal channel.
