这部分代码主要实现了TURBO码的编解码，运用max-log-map译码方法进行译码-this code realise the encode and decode function of turbo,the decoding algorithm is by max-log-map

实现了LTE的turbo码的编解码,对数据进行编码，然后再对其进行译码，是通过MATLAB来实现的，适用于4G下-Codec implements LTE turbo codes to encode data, and then decodes, by MATLAB to achieve, under applicable 4G
