Зниження обчислювальної складності декодування для турбо-кодів стандартизованих DVB-RCS

Abstract

Considered problems, associated with modern methods of turbo coding, promising for use in communication systems. Displaying the principles of work taking into account the satellite standard DVB-RCS. Considered algorithms, that reduce computational complexity, log-MAP and max-logMAP. Obtained a generalized expression for calculating the log-likelyhood ratio in the process of decoding procedures using probabilistic research and energy characteristics of information transfer. Modeling the use of such methods decoding turbo codes in the technique of using computing power facilities and proof the necessity of these algorithms.
