A ML/DFE and iterative spatial interference cancellation for 2×2 BICM MIMO system

Abstract

In this paper, we propose a low complexity iterative two transmit and two receive MIMO detection technique achieving full coded ML performance for bit interleaved coded modulation (BICM) based MIMO system. Unlike the conventional iterative SIC/HIC-MMSE decoding approach, the update corresponding LLRs in iterative mode. From computer simulation results, our proposed iterative scheme outperforms previously proposed iterative receivers as well as full coded ML detector.
