Soft Decision-based Data Detection Scheme for NR Communications System

In this paper, the low-density parity-check code and 256 QAM of new radio (NR) technology were applied to meet the high reliability and high data-rate requirements of 5G communications systems. In addition, we propose a data detection scheme based on a soft decision to improve the reliability. The simulation results show that the proposed data detection scheme can improve the error rate and throughput of a conventional system.
