对输入随机数字信号进行卷积纠错编码后，送入含噪信道，在接收端再进行解码和检纠错，改变信道误码率大小，测试接收信号与发送信号之间的误码率，分析该种纠错编码系统的抗噪声性能。-After random input digital signal convolution error correction coding into the noisy channel, at the receiving end and then decode detection and correction, changing the channel error rate BER size, test the received signal and transmit signal, analysis of anti-noise performance of this kind of error correction coding system.
