摘要
为了提高电力线通信的可靠性,采用BCH码和交织相结合的纠错编码技术来降低通信的误码率。在分析了一般BCH码编译码原理的基础上,提出了一种改进的编译码软件设计方案,选用了合理的交织技术并通过仿真验证了BCH码结合交织技术的可行性。利用ARM芯片结合FPGA实现了该交织编码方案,结果表明该系统可以同时纠正一帧数据的随机错误和突发错误,提高了电力线传输的可靠性。
In order to improve the reliability of the power line communication, the bit error rate was reduced by a scheme of BCH coding and decoding integrated with interleaving, a improved method of BCH coding and decoding was presented. Based on the analysis of the scheme of BCH coding and decoding integrated with interleaving, a reasonable interleaver was chosen and the feasibility of this scheme was validated by MATLAB. The scheme of the interleaved coding were realized with ARM chip integrated FPGA. Moreover, frame synchronization was detected by FPGA. Both the random error and burst error were corrected, so the reliability of power line communication was improved.
