应用C语言对（7,3）线性分组码的编译码的软件设计。主要做了以下几项工作：对三位正确的信息码进行编码；若输入的三位信息码有错，系统输出提醒，可以重新输入；对七位接收到的码字判断是否有错，并在无错和有一位错误时进行译码，在有多位错误时输出提醒，可以选择重新输入。-Application of C language for encoding and decoding (7,3) linear block code software design. Mainly to do the following work: three of the correct information is encoded code　if three information code entered is wrong, the system outputs a reminder, you can re-enter　for seven received codeword to determine whether there is wrong, and when performed error-free and there is a decoding error, the error output has more than a reminder, you can choose to re-enter.
