A novel cooperative diversity scheme based on irregular low density parity check code(LDPC) design is proposed in this paper, and three different relay protocols of one user and one relay numerical results of bit error rate and outage probability for the quasi-static rayleigh fading channels are also presented by theoretical derivation and system simulation. Compare and analysis the bit error performance and outage probability simulation graphs of two-users multi-relays using coded cooperation strategy.results that through integrating with irregular LDPC and cooperative MIMO,bit error rate and outage probability decreased greatly.the performance improved significantly.
