Abstract :
The paper describes a fast modulation recognition technique for use in Rayleigh fading channels. To achieve fast and accurate modulation recognition, we propose the optimum threshold for symbol selection in fading channels. The result is a 20% reduction in recognition time with high recognition accuracy.
