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.

MIMO-LDPC系统的低复杂度联合检测与解码算法
联合检测与解码(JDD)算法由于其优异的性能近年来受到了广泛的关注。针对第五代通信系统对高速率、低时延的要求,提出了一种适用于MIMO-LDPC系统的低复杂度联合检测与解码(LCJDD)算法。该算法的计算复杂度明显低于使用JDD块的系统,性能损失可控制在0.5 dB左右。
