Abstract：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.
