Performance Evaluation Parameters Analysis for Trellis Coded Modulation Systems

The newer applications of Trellis Coded Modulation (TCM) beyond 5G has triggered the research activities for further inventions in this area. As a result, the inventions and research analysis on different aspects of the technique is in boom. This paper analyzes various performance evaluation parameters as applicable to coded modulation schemes which can be structured as a finite state machine. The significances of the parameters are discussed and the measurements through simulation are evaluated. Tradeoff between the decoding computational complexity and the codinggain factor improvement has been analyzed.
