Performance evaluation of LDPC coded MIMO transceiver with equalization

Abstract

A Multiple Input, Multiple Output (MIMO) system has multiple antennas and multiple radios. In MIMO systems, data will arrive at the receiver at different times through different paths to improve the quality of the data link. MIMO technology has attracted attention in radio communications, because it offers significant increases in data throughput and link range without additional bandwidth or increased transmit power. In the MIMO system, forward error correction coding is essential for high data rate communications. Recently, low-density parity-check (LDPC) codes have attracted much attention as good error correcting codes. In this paper, we propose a new LDPC coded MIMO system with equalization such as minimum mean square error (MMSE) and maximum likelihood detectors (MLD). Simulation result show that the coded MIMO system with MLD can achieve the good error rate performance comparing to coded MIMO system with MMSE.
