What do you understand by trellis Coded modulation explain details?

Trellis coded modulation (TCM) combines modulation and encoding processes to achieve better efficiency without increasing the bandwidth. Bandwidth-constrained channels operate in the region R / W > 1, where R = data rate and W = bandwidth available.

What are the advantages of trellis codes?

Trellis coding offers a means of increasing data rate without increasing transmitted bandwidth. This is ideally suited to experimental verification. The gain is achieved with multi-level, multi-phase signalling.

What is the significance of trellis diagram?

The trellis diagram shows every possible sequence of state transitions of the state diagram.
