联合LDPC码和网络编码的协作通信技术
Joint LDPC codes and network coding cooperative communication technology
摘要
Abstract
Combining the idea of channel coding and network coding, a joint LDPC codes and network coding cooperative diversity scheme in the scenarios of two-user collaboration is proposed in this paper. The joint decoding of LDPC codes and network coding is implemented by using belief propagation algorithm on its overall H matrix in the receiver. The bit error rate performance of the system in Rayleigh slow fading channel was verified through MATLAB simulation, which shows a significant improvement of the proposed scheme over the non collaboration and coding cooperation systems.关键词
