Construction of LDPC Codes for Coded Cooperative Relay

摘要

In this paper, we present two construction schemes for LDPC codes in coded cooperative communication. The scheme which uses rate compatible LDPC codes based on puncturing parity bits is presented first. Then the paper proposes the scheme which uses QC-LDPC codes based on the multiplicative inverses in finite fields. Detailed implementations of two schemes are presented. Simulation results show that the LDPC codes constructed by these two schemes are valid in coded cooperation.
