仿真（2，1，2）卷积码编解码器在二进制对称信道（BSC）中的误码性能，画出纠错后误码率-信道误码率曲线，其中，编码器的生成多项式为g1=[111]、g2=[101]。-imulation (2,1,2) convolutional encoding and decoding the binary symmetric channel (BSC) in the error rate performance, bit error rate after correction drawn- the channel bit error rate curve, which generated a number of encoder formula g1 = [111], g2 = [101].
