摘要
针对CTCS3级列车控系统中无线信道的信息安全传输问题,本文设计了Turbo码的CTCS3级列控系统无线信道的信息安全传输方案,并分别采用了SOVA译码算法、Max-Log-MAP译码算法、Log-MAP译码算法进行仿真测试与比较分析,验证了该方案的合理有效性。仿真结果表明,采用Turbo码技术,可以降低无线信道中误比特率,满足列控系统数据传输的要求,提高系统的可靠性。
In terms of the problem about the information secure transmission in wireless channels for CTCS3 Train Control System, Turbo codes based resolution was designed. In addition, this paper demonstrated simulation testing and comparative analysis by using SOVA decoding algorithm, Max-Log-MAP decoding algorithm, as well as Log-MAP decoding algorithm respectively, which further verified the rationality and validity effectively.
