前向纠错（FEC）主要用于提高信道的传输性能，在ATM信元头中有CRC纠错方案HEC，但是主要是针对光纤等优良信道，对于干扰严重的无线信道，应有更有力的纠错方案。本文是在信道编码方案确定的条件下，提出进一步提高纠错能力、降低信无丢失率的方法。
Forward error correction (FEC) is mainly used to improve the channel transmission performance, CRC error correction scheme in the ATM cell header HEC, but mainly for good channels such as optical fiber, for serious interference wireless channel, there should be more powerful Error correction program. In this paper, under the conditions of the channel coding scheme, we propose a method to further improve the error correction capability and reduce the lossless rate.
