基于串并结合策略的SCMA多用户检测
SCMA Multiuser Detection Based on String Parallel Combination Strategy
摘要
Abstract
Sparse Code Division Multiple Access(SCMA) is an important wireless air port technology support for the development of the fifth generation mobile communication system,which can meet the needs of mass connection.Aiming at the problem of system delay based on the serial Message Passing Algorithm(MPA) used by the receiver of the uplink SCMA communication system,a combined serial SCMA multiuser detection (MUD) algorithm is proposed by full integration of serial parallel MPA.The simulation results show that compared with the serial MPA MUD algorithm,this proposed algorithm can reduce the complexity of the sys-tem,and reduce the run time of each iteration to reduce the system delay.Furthermore,the ideal balance be-tween bit error rate(BER) performance and system latency,system complexity is achieved.关键词
