Abstract :
Trellis-coded modulation (TCM) is defined and described with respect to code-to-signal mapping and coding for QAM. Also summarized are the evolution and underlying principles of TCM and how TCM schemes achieve coding gains without bandwidth expansion. An example is used to illustrate a simple implementation of such a coding scheme
