摘　　要：介绍了一种典型级联码的编码方式,讨论了编码的纠错能力,针对此纠错能力,阐述了对该级联码干扰时所采取的两种干扰方式:同步干扰和脉冲干扰,给出了两种干扰方式的比较精确的干扰脉冲宽度,以及两种干扰方式分别带来的干扰效果。同步干扰方式可以影响到解码时同步字节搜索的过程,进而影响解码过程;脉冲干扰可以使解码后数据流产生误码,进而使传输数据受损。A typical concatenated code is introduced and the error-correcting capability of the code is discussed in the paper. The methods of synchronous interference and pulse interference are stated according to the er- ror-correcting capability of the concatenated code, and the more precise interference pulse width and the in- terference effect of the two methods are given. The synchronous interference influences the search process of synchronous bytes, which leads to the influence of decoding process and the pulse interference makes the code error of the decoding data, which leads to the loss of transmit data.
