Trellis-Coded Modulation, TCM, combines the processes of modulation and encoding to achieve an overall coding gain that is usually greater than that achieved by performing the operations independently. This paper is concerned with utilizing TCM and 8-PSK to achieve a spectrally efficient modulation scheme with a constant envelope. Since TCM involves Euclidean distance as a metric, the concept of a quantized decoder is developed to decrease the decoding time.Sponsors
