| Abstract: | This paper introduces a new idea of converting RF to IF, samplings the analog signal into digital signal. And then it researches the acquisition, tracking and position resolution based on DSP technology. Through the design of GPS software receiver and signal processing, it is shown that the high flexibility in algorithms and software can be realized based on software radio technology, and the system performance of GPS receiver can be developed. |
