Abstract This paper presents a new method of fast code acquisition under low SNR, and large Doppler shift condition. The method gives decision base on the peak existence in the spectral of instant correlation between the local code and the zero-IF received signal. This scheme not only promises a performance as good as that of parallel channel optimum receiver but also has a much simpler structure.
