An error control protocol based on trellis coded modulation

A novel rate-adaptive hybrid error control technique for mobile radio applications is presented. Instead of using a binary forward error-correcting code in conjunction with a binary modulation scheme, the error control system uses joint power and bandwidth efficient trellis-coded modulation in the inner coding subsystem. As a result, the throughput of the error control system, operating in a Rayleigh fading channel environment, is better than that of many previous systems at the ranges of signal-to-noise ratios of interest. Analytical and simulation results for the throughput of systems that use different trellis-coded modulation schemes are presented and compared with previous results
