摘要

对卫星通信系统中的SCMA检测算法进行研究，提出将码本优化分配与不完全迭代MPA算法联合检测，在提升系统性能的同时降低系统复杂度。同时，对SCMA检测算法的收敛性进行研究，提出改进的串并结合MPA算法，该算法能够加快系统收敛速度的同时降低处理时延，并且系统复杂度得到了降低。

Abstract

SCMA detection algorithms in the satellite communication system was studied

and optimal allocation of codebook and the incomplete iterative MPA detection algorithm were combined to improve system performance while reducing system complexity.The convergence of the SCMA detection algorithm was studied

and an improved serial-parallel MPA algorithm was proposed.This algorithm could accelerate the system convergence speed while reducing the processing delay

and the system complexity was also reduced.
