摘　　要：在协作通信技术与信道编码技术基础上,对分布式信道编码进行了介绍并构造了分布式RS码系统。基于子空间理论,在分布式编码系统的目的点处联合构造码字。利用RS码是MDS码的特性,提出了一种中继信息选择算法来优化中继信息选择方式,从而在目的点处获得一个重量分布相对较优的码字集合。此外,基于信道编码特性,在目的点处提出了两种联合译码算法。最后通过Matlab仿真验证了中继信息选择算法对分布式RS码系统性能的改善,并比较了两种联合译码算法之间的性能。This paper constructs a distributed RS code system based on cooperative communication technology and channel coding technology.Based on the subspace theory,a codeword set with better weight distribution is constructed at the target point of the distributed coding system.Utilizing the characteristics of the RS code as the MDS code,a relay information selection algorithm is proposed to optimize the relay information selection method,therefore the destination can obtain optimize.In addition,based on the characteristics of channel coding,two joint decoding algorithms are proposed at the destination.Finally,through Matlab simula⁃tion,the relay information selection algorithm is verified to improve the performance of the distributed RS code system,and the per⁃formance between the two joint decoding algorithms is compared.
