Abstract

Multiple-input multiple-output (MIMO) bit-interleaved coded modulation (BICM) has been proposed to apply in fast-fading environment. In this paper, we investigated the link-level capacity (LLC) and bit-error-rate (BER) performance of MIMO BICM system with soft-output MMSE soft interference cancellation (SIC) detection. We compared two SIC schemes in this paper. The first one is ordering successive SIC, in which the transmitted symbols are detected sequentially with post-detection signal-to-noise ratio (SNR) based ordering and interference cancellation error compensation. In the second scheme, we proposed to perform parallel interference cancellation (PIC) and detect the transmitted symbols simultaneously. We compared the LLC and BER performance of different detection schemes through extensive simulation.
