这里实现的是ldpc的软判决算法(归一化最小和算法),输入的是8bit量化的软信息,而不是0/1。可以根据实际的信道计算软信息,然后将其量化为8bit即可。

非常感谢您的快速回复,不过我对各种术语也不太明白,您的意思是这8位相当于是把信息从0到1划分为256份,然后这个模块的输出是用类似最大似然的方式估计出来的数据么?
如果我想仅仅只是先实现功能,输入1536bit,输出1024bit,把你的测试数据中正数作为1负数作为0就行么?
然后这样用肯定性能很糟糕,浪费了八倍的输入,如果要做一个适合于1536bit的解码器,我是应该了解一些硬判决算法重新实现,还是您的这份代码其实也可以简单修改为硬输入的呢?
十分感谢

你的理解是对的。直接采用正负1作为输入也是可行的,但是不是最优的。具体采用什么算法,需要结合具体的应用,建议先了解一些基本的算法,结合应用场景选择合适的进行实现。
