（7，4）系统循环码译码器 decode_out = cyclic_decoder(decode_in) 该系统循环码译码器的生成多项式是g(x) = x^3 + x + 1 输入参数decode_in是接收到的循环码字，是1×7的行向量；输出decode_out是解 码后的信息码字，是1×4的行向量。 函数运行时，同时画出接收循环码字和译出码字的波形图。 ( (7,4) system cycle Decoder decode_out = cyclic_decoder (decode_in) cyclic code decoder of the system generating polynomial is g (x) = x ^ 3+ x+ 1 input parameters decode_in is the received codeword cycle, the row is 1 × 7 vector output decode_out solution code is the information after the code word is 1 × 4 row vector. Function to run at the same time code word and draw a circle to receive the word of the translated code waveform.)
