Broadband wireless packet access will be the core technology of the next generation mobile communications systems. Very high speed and high quality packet transmissions can be achieved by the joint use of multiple-input multiple-output (MIMO) multiplexing and hybrid ARQ (HARQ). However, if single-carrier (SC) transmission is used, the throughput performance significantly degrades due to large inter-symbol interference (ISI) resulting from severe frequency-selective channel. Recently, we proposed an iterative parallel interference cancellation (PIC) for MEMO multiplexing in a frequency non-selective fading channel. In this paper, we propose a frequency-domain iterative PIC for SC-MIMO multiplexing to separate signals transmitted from different antennas while achieving frequency and antenna diversity gain and evaluate, by computer simulation, the throughput performance of turbo coded HARQ using SC-MIMO multiplexing in a frequency-selective Rayleigh fading channel.
