Abstract. The problem of list decoding of turbo codes is considered. A new algorithm of window-based list decoder of convolutional code with soft output is developed in the frames of the parallel turbo decoding method. The proposed algorithm is shown to outperform the algorithm presented earlier; the gain in performance is obtained not only with short words, but also with words of considerable length.
Keywords: turbo codes, turbo decoding, list decoding
