摘要：
The features of the received signal in the LDPC-COFDM MIMO system with space-time block coding(STBC) was analyzed in this paper, the signal estimate of the received signal obeys Gaussian distribution and it has nothing to do with the statistical distribution of the specific channel. According to the features of the received signal, a new decoding algorithm of LDPC for COFDM-MIMO system is proposed. The performance of the algorithm is detailed analyzed in the case of different bit rates and compared with other decoding schemes. The simulation results show that the algorithm can greatly reduce the number of iterations, and improve the decoding speed. Furthermore, the algorithm has the good decoding performances and the adaptability of different code rates.
