For solving the problem that P-code direct acquisition with low signal-to-noise rate in high dynamic environment|,the article provided a new P-code direct acquisition system that jointed non-coherent accumulate and FFT processing for part-correlation value based on matched filter.

But,P-code direct acquisition should be implemented in GPS receiver in order to achieve the higher spectrum-spread gain,the better anti-deception and anti-spoofing,without needing to rely on the other short-code to capture.

Basing on researching the structure and the characteristics of P code,the more effective acquisition algorithms were analysed,and a new fast direct acquisition algorithm has been proposed.

On the TC/MAX criterion for code acquisition and its application to UWB systems;

Presents a new code acquisition method to solve the problem of long code-acquisition time in high dynamic DSSS receivers having large frequency offset.

It is studied that the code acquisition technology of direct sequence spread spectrum system in LEO satellite communication.

Study on one DS-SS PN Code Acquisition System;

PN code acquisition method based on prepositive 3-order correlated detection

This paper proposed a PN code acquisition method based on IF sampling to implement a new type of satellite receiver.
