输入信号的时域和频谱分析 输入信号为ft=[5cos(600*pi*t)+4cos(90*pi*t)+9]/18 输入信号为高频和低频信号的叠加：高频300Hz，低频45Hz( Of the input signal in time domain and spectral analysis of the input signal is ft = [5cos (600* pi* t)+4 cos (90* pi* t)+9]/18 input signal for the high-frequency and low frequency signal superimposed: frequency 300Hz, 45Hz low frequency)

After identifying the best MNT− 1 nodes with the simplified branch metric and the accumulated branch metric at stage NT − 1, we then calculate the LLR of each coded bit utilizing the standard squared Euclidian distance metric. The log-likelihood ratio (LLR) of a posteriori probability (APP) of each coded bit conditioned on the received signal y is normally calculated using the max-log approximation.
