Abstract :
Channel coding always plays an important role in communication systems. Decoding complexity is one factor which needs to be considered in its implementation. In this paper the decoding algorithm for MTCM is studied. Viterbi decoding algorithm for MTCM contains much more computations per trellis state transition. A most applicable decoding scheme for MTCM is proposed, which can achieve reduced computational complexity. The BER performance can approach that of the maximum likelihood decoding algorithm quickly by increasing the value of one parameter of MTCM.
