基于循环相关熵谱的MSK信号能量检测算法
Research on Energy Detection Algorithm of Msk Signal Based on Cyclic Correntropy Spectrum
摘要
Abstract
Aiming at the degradation of traditional energy detection algorithms under the influence of non-Gaussian noise background,an energy detection method based on cyclic correntropy spectral density function is proposed.In this paper,the good suppression ability of non-Gaussian noise by cyclic correntropy function is used to detect the energy of MSK signal by intercepting the cyclic correntropy spectrum tangent surface on the zero-frequency axis,which overloads the received signal power caused by non-Gaussian noise and causes the failure of conventional energy detection methods.Computer simulation results show that the proposed algorithm has better detection performance under low generalized signal-to-noise ratio and strong pulse noise.关键词
