说明：  内容概述：未编码传输AWGN信道测试 每帧的输入是相同的，（不是每帧都不一样，这样可以大幅降低计算量） 在帧比特足够多的情况下，应该可以保证随机性
(Description of content: the transmission of uncoded AWGN channel test The input of each frame is the same, (not every frame is not the same, so you can significantly reduce the computational load) Enough in the frame bit should be able to guarantee randomness)
