摘　　要：根据传统的前向纠错方式(FEC)方式的GOLAY码纠错方法进行改进,提出了在无线短波数据传输中提高传输性能、降低误码率的方法。该方法经过北京-九江1000多km无线短波自适应数据传输系统多次试验,并通过软件实现方法使(23,12:7)达到了(23,12:8)的性能。给出了实验数据,并论述了自适应短波数据传输中的编码和纠错方法的前景。An improvement for FEC GOLAY codes is described, and a method of decreasing data transmission error ratio is proposed.The method has been proved in the radio test of over 1000 kilometers from Beijing city to Jiujiang city,and it can improve the performance of GOLAY coding through cross correction. The radio test data are provided, and the prospect of coding and error correction in adaptive shortwave data transmission is described.
