TCM Encoding Modulation End with 8PSK and 2/3 Rate Convolutional Code

This MATLAB program implements the modulation end of TCM (Trellis Coded Modulation) encoding using 8PSK modulation scheme combined with a 2/3 rate convolutional code. The implementation employs advanced modulation techniques where input signals are encoded through 8-phase shift keying (8PSK) constellation mapping, while integrating a rate 2/3 convolutional encoder to significantly improve error correction performance. The code structure includes key components such as convolutional encoding with appropriate generator polynomials, symbol mapping to 8PSK constellation points, and modulation waveform generation. Developed in MATLAB, this program facilitates simulation and experimental analysis of TCM encoding at the modulation end, providing researchers with practical tools to thoroughly understand and investigate TCM encoding principles, performance characteristics, and implementation considerations. Through utilization of this program, users can effectively study bit error rate performance, spectral efficiency, and trade-offs between coding gain and complexity in TCM systems. We hope this implementation proves valuable for your research and development activities!
