Abstract :
The authors discuss the use of quantized Euclidean soft-decision maximum-likelihood sequence decoders on trellis-coded 8-PSK communication schemes. A model is developed for the circularly quantized Euclidean decoder, and computer simulations are used to evaluate it. Degradation is determined as a function of the number of sectors used in the circular quantization.<>
