1.	The TCM decoder uses(a) Minimum likelihood detector(b) Maximum likelihood detector(c) Does not use redundant bits(d) None of the mentionedI had been asked this question in homework.This intriguing question comes from Trellis Coded Modulation topic in section Modulation and Coding Trade-off of Digital Communications
Answer» Correct choice is (b) Maximum likelihood DETECTOR To elaborate: The task of convolutional DECODER is to estimate the path that the MESSAGE had traversed through the encoding trellis USING maximum likelihood detector.
