| 摘 要： | 目前P码的捕获通常是利用C/A码来完成.为保证扩频信号具有更高的扩频增益、更强的抗模仿和抗欺骗能力,必须实现P码的直接捕获,而不依赖于其他短码来捕获.本文从研究信号直接捕获算法角度出发,提出了一种新的P码快速直接捕获算法.仿真结果表明:该算法能够达到有效的P码捕获.

| Abstract: | P-code is usually acquired depending on C/A code.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.A new P-code direct acquisition algorithm is proposed by studying direct signal acquisition algorithms.The simulation result shows that the algorithm is effective. |
