A Fast Blind Detection Algorithm Based on CFAR for Multiple Satellite Signals
摘要
Abstract
A fast blind detection algorithm of multiple satellite signals is proposed in this paper.The algorithm can easily ob⁃tain signals counts and carrier frequency in real time under certain signal to noise ratio. The algorithm estimates the statistical characteristic of the noise based on CFAR accurately and sets the threshold of signal⁃noise separation. It detects the blind sig⁃nals successfully according to the actual bandwidth characteristics finally. The simulation results show that the algorithm can detect the blind signals quickly and accurately. Compared with other algorithms, it has high accuracy, strong commonality and can meet the needs of The actual project better.关键词
