Maximum Likelihood of Gaussian Distribution for log returns

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-lik

This function implements the composite objective measure proposed in [1]. It returns three values: The predicted rating of overall quality (Covl), the rating of speech distortion (Csig) and the rating of background distortion (Cbak). The rat
