摘要
在循环平稳理论的基础上,根据BPSK信号的谱相关函数及其在普通傅立叶频率和循环频率双频率平面上所表现出的谱线特征,提出了一种在高斯白噪和QPSK干扰信号中识别BPSK目标信号的识别算法。该方法以中频信号为处理对象,抗噪和抗干扰能力较强,计算机仿真表明了该方法的可行性.
In this paper a novel identification method for BPSK signal with known parameters in WGN or QPSK- interference environments is proposed based oh spectral correlation and the characteristics of the spectral lines on the bifrequency plane.The method can be used directly for IF signals and with improved anti-noise and anti-jamming performances.The algorithm is described and discussed,and finally,the simulations results are provided and prove the feasibility of the algorithm.
