摘要
多系统兼容并存的发展趋势对接收机的性能提出了更多要求,软件接收机以其方便性与灵活性将取代使用ASIC的硬件接收机成为发展新方向。文中基于GPS软件导航接收机进行了信号捕获算法研究。采用双驻留滑动相关法,在Matlab仿真环境下对卫星数据进行捕获,实验结果表明了捕获方案的正确性和有效性。
The compatible development trend with the coexistence of muhiple systems requires additional performances of the receiver. The software receiver will take the place of the hardware receiver using ASIC and become the direction of the receiver development with its convenience and flexibility. GPS signal capturing based on software GPS receiver is investigated. The Double Dwell Sliding Correlation Method is used to capture the satellite data in the MATLAB. The simulation results prove the correctness and effectiveness of this acquisition algorithm.
