摘要
针对OTDR系统高信噪比的要求,提出一种将Si mpl ex编码与CCPONS编码相结合的C-S复合码。分析了C-S复合码的产生方法及其应用于OTDR系统的编码解码原理,推导了引入C-S复合码的OTDR系统信噪比增益,实现了在有限编码长度下大幅度提高系统信噪比的目标。
According the requirements of high signal-to-noise ratio (SNR) for OTDR system, the paper propos- es a compound C-S coding scheme which combines CCPONS and Simplex coding. The C-S code generation method is introduced and its coding and decoding principle applying to the OTDR system is analyzed. The SNR gain of the OTDR system is derived after induces the C-S code, achieves the target of improving the SNR of the system with the limited coding length.
