对（7，4）循环码的误码率进行了matlab的仿真，通过对比两条曲线，直观对比出未经过信道编码和经过信道编码的误码率比较。-Of (7,4) cyclic code error rate of the matlab simulation, by comparing the two curves, a direct comparison has not been after channel coding and channel coding the bit-error rate.

实现信道编码仿真，有卷积码，汉明码，循环码，比较器误码率-Achieving channel coding simulation, there are convolutional codes, Hamming codes, cyclic codes, error rate comparator

循环码的编码与译码器(支持一位的纠错) 编码(n,k可调) 测试用例1： input:n=7 k=3 g=11101 m=101 output:1010011 input:n=7 k=3 g=11101 m=010 output:0100111 测试用例2： input:n=7 k=4 g=1011 m=1101 output:1101001 input:n=7 k=4 g=1011 m=1010 output:1010
