Abstract

It is considered BCJR algorithm of convolutional codes by criterion of a maximum posterior probability. Analysis of probabilistic characteristics of this algorithm with its simplified variant is carried out. The computational complexity of the given algorithm for realization on microprocessor ADSP BF-533 is shown.
