Frequency-Domain Iterative SIC for SC-MIMO Multiplexing

Recently, the multi-input multi-output (MIMO) multiplexing technique has been gaining much attention for achieving very high speed data transmissions in a bandlimited wireless channel. However, if single-carrier (SC) transmission is used, the bit error rate (BER) performance significantly degrades due to inter-symbol interference (ISI) resulting from a severe frequencyselective fading channel. Recently, we proposed a frequency-domain iterative parallel interference cancellation (PIC) for SC-MIMO multiplexing to separate signals transmitted from different antennas while achieving frequency and antenna diversity gain. In this paper, we present a frequency-domain iterative successive interference cancellation (SIC) and evaluate, by computer simulation, the BER performance in a frequency-selective Rayleigh fading channel.
