摘要:
针对RS+卷积级联码译码性能在“比特级”层面研究较少的问题,提出了利用错误图样分布来研究其译码性能的方法。该方法在不加调制的情况下,通过设定错误图样参数,分析了不同参数下错误图样分布对其译码性能的影响;在此基础上又对突发错误下加入交织器的级联码系统进行了对比分析。仿真结果表明,错误图样的不同分布会对此级联码的译码性能产生不同的影响,突发错误下内交织器更有利于级联码的纠错。
Abstract:
Aiming at the problem that few studies on the decoding performance for concatenated RS-convolutional codes in "bits" level, a method which using the error pattern distribution to analyze the decoding performance was proposed. The influence of error pattern distribution was analyzed on the decoding performance by setting parameters without modulation. Also the decoding performance of the system which added different interleavers was investigated under the burst error on that basis. Simulation results showed that different error pattern distribution had different influences on the decoding performance, and the inner interleaver could enhance the correcting ability.
