Abstract

This paper presents an automatic recognition algorithm of analogue modulated signals provided that jamming signals exist near the carrier frequency of a target signal. The proposed algorithm is based on the decision-theoretic approach, is assumed to be used as surveillance system for radiowaves, and can distinguish LSB (lower side band), USB(upper side band), AM (amplitude modulation), and DSB-SC (double side band suppressed carrier). The performance of the proposed algorithm is evaluated through some simulations of modulation recognition.
