基于自制小波的EBPSK信号检测器
A novel EBPSK signal detector based on custom wavelet
摘要
Abstract
Aiming at the key difficult problem of detecting ting modulation differences of the extended binary phase shift keying (EBPSK) modulation,a novel high-speed and high-efficiency modulation scheme,this paper proposes a new EBPSK signal detector based on custom wavelets,and the custom wavelets are constructed in the light of the envelop of impacting filtered EBPSK modulation waveforms.The custom wavelet based detector was compared with the ones based on typical wavelets by simulation,and the results showed that the proposed custom wavelet based detector exhibited the best performance over additive white Gaussian noise (AWGN) channels.The detector can also well detect the position and scale signals in low SNR cases,and its computational complexity is lower.关键词
