针对现有扩频信号捕获方法实时性差、消耗硬件资源多的缺点
提出了一种基于FFT的低信噪比扩频信号快速捕获方法.根据FFT原理
设计了FFT伪码捕获原理框图
并从伪码特性、FFT栅栏效应和信道影响三方面分析了其性能.仿真结果表明:FFT捕获算法在-10 dB的低信噪比下仍具有良好的伪码捕获性能
并具有一定的实时性
可广泛应用于无线定位、遥控遥测和卫星通信等领域.
A spread spectrum signal acquisition method based on FFT was proposed in view of the existing methods with poor real-line performance and large hardware consumption.According to the principle of FFT
the acquisition scheme was designed and the characters were analyzed from PN code
FFT stockade effect and channel effect.The simulation result shows that the FFT acquisition algorithm can realize PN code acquisition in a low SNR of-10 dB
and has secrecy and anti-jamming capability.The method may be widely used to the fields of wireless positioning
remote measurement and control and satellite communications.
