Abstract :
Signal detection in low signal to noise ratio (SNR) is widely concerned. In this paper, an algorithm for weak signals detection based on cross-correlation analysis is proposed. The simulation results show that this algorithm is a fairly effective method for improving the ratios of signal to noise. Using this algorithm in radio monitoring, we can raise the sensitivity of the monitoring system and extend the regional coverage of the radio base station.
