从均匀PCM方法入手，产生一振幅为1和频率ω=1的正弦信号，分别用8电平和16电平进行量化，在同一坐标轴上绘出原信号和以量化信号，并比较这两种情况下的信号/量化噪声比(Starting from the uniform PCM method to produce a 1 amplitude and frequency ω = 1 of the sinusoidal signal, respectively, with 8 levels and 16 levels were quantified in the same plot of the original signal and the axes to quantify the signals, and to compare these two cases, the signal/quantization noise ratio)

由于硬判决在判决过程中将接收直接判决为[1 0],而损失了相应的近似信息，导致了接收信息在某种意义上的浪费。软判决将接收电平量化，尽可能保存相应的信息，故可以提高译码性能。(soft descision decoding)
