Zusammenfassung:	The constant log-MAP decoding algorithm suitable for duo-binary turbo codes. Motivated by an existing algorithm approach, an efficient algorithm is presented, which is superior in terms of frame/bit error rate performance and has approximately the same computational complexity. Compared with log-MAP decoding, the proposed algorithm has negligible performance degradation, exactly as for binary turbo codes.
