摘要

针对目标信号载波频率附近存在干扰信号的情况,提出了一种模拟调制信号的自动识别算法。该算法基于决策理论,假设用于无线电波监控系统,能够区分LSB(下频带)、USB(上频带)、AM(调幅)和DSB-SC(双频带抑制载波)。通过调制识别仿真,对该算法的性能进行了评价。

An automatic recognition algorithm of analogue modulated signals for disturbance rejection
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.
