Abstract

This paper presents Dayan sequence to construct QC-LDPC codes through the combination of mathematical theory. The paper introduces the procedure of the coding principle and coding. Dayan sequence constructed QC-LDPC codes is compared with rate compatible QC-LDPC, Simulation results show that the bit error rate (BER)performance of Dayan sequence constructed QC-LDPC is improved by 0.5dB. Then QC-LDPC codes constructed by the Dayan sequence are used in coded cooperative communication. Compared it with PEG algorithm, array code and Mackey code,the results show that the performance of Dayan sequence is superior. That is to say that Dayan sequence code constructed QC-LDPC is effective in coded cooperative communication.
