用MATLAB软件分析音频信号通过高通滤波前后的频谱(Using MATLAB software analysis audio signal through the high-pass filtering of the spectrum before and after)

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.
