About this document
TCM and Trellis Code Modulation Overview by Tran Hung is a document available to read on EtoBox.
This document discusses convolutional coding and trellis code modulation (TCM). It begins with an overview of convolutional coding basics like encoder state diagrams and trellises. It then introduces TCM, which combines modulation and finite state encoding to achieve coding gains without additional bandwidth. TCM assigns modulation waveforms based on the encoder state to optimize Euclidean distance. The document traces the evolution of TCM since its invention in 1976 and discusses techniques like set partit
