摘要
介绍了煤矿数字视频监控系统的构成,提出了将LDPC码应用到煤矿数字视频监控系统的信道编码中,利用FPGA实现信道编码部分构成,其能有效地纠正井下数字通信中常见的突发错误,对提高井下通信的可靠性有着重要作用。
This paper introduces the Structure of digital video monitoring-control system in coal mine,for a proposed LDPC codes will be applied to channel coding in the system.The use of FPGA implementation of channel coding parts can effectively correct underground digital communication common in emergencies errors.It will play an important role in improving the reliability of underground communications.
