摘要
针对煤矿通信环境复杂多变的特点,结合LDPC码描述方便、易于进行理论研究的特点,利用乘积码的编译码原理,设计了一种基于LDPC码的联合网络编码,并在多址接入中继网络中通过仿真证明,该设计能大大降低误码率,从而提高网络性能。
According to the complicated coal mine communication system and LDPC(Low Density Parity Check Codes) is easy to describe and study. Using the product code decoding principle, a joint network coding based on LDPC codes is proposed. Through the simulation and verification in the Multiple Access Relay System, the results show that the error rate is reduced and the performance of the network is improved.
