Abstract
To extract the available parameters of conventional communication signals from complex electromagnetic" circumstance, a real-time sorting method of conventional communication signals, based on a single received channel, is proposed. The sorting method consists of three parts, narrowband signal detection, parameter estimation and tracking. Hence, a detection and parameter estimation method of narrowband signals is first proposed in additive Gaussian color noise. A narrowband signal tracking algorithm is then discussed which is able to track conventional communication signals in real time. At last, the simulation results show that the ratio of correctly detecting the number of narrowband signals is not less than 92% at signal-to-noise ratio (SNR) 0 dB. The sorting method is able to obtain the available parameters of conventional communication signals from complex electromagnetic circumstance, and valuable in practical engineering.关键词
