A Low Complexity Joint Detection and Decoding Algorithm for MIMO-LDPC System

Abstract

Joint detection and decoding (JDD) algorithm has recently received extensive attention due to its excellent performance. Responding to the requirements of the 5thgeneration communication system with high rate and low latency, a low complexity joint detection and decoding (LCJDD) algorithm for MIMO-LDPC system has been proposed. The computational complexity of the proposed algorithm is significantly lower than that of systems using JDD blocks, and the performance loss can be controlled to be within about 0.5 dB.
