摘要
提出了基于软件无线电的伪卫星接收机的数学模型和数字平台实现的两种方案:DDC+DSP方案和FPGA+DSP方案。通过对这两种方案的比较,得出在伪卫星接收机数字平台的设计中应采用FPGA+DSP方案。
The mathematic model for a Pseudolite (PL) receiver based on software defined radio (SDR) is presented, and two schemes for realizing the digital platform are proposed which are DDS + DSP and FPGA + DSP. Comparison of this two schemes shows that the scheme of FPGA + DSP is better for the digital platform of PL receivers.
