| Design and Realization of Pseudolite Receivers Based on Software Defined Radio(SDR) |
|
| () |
| Abstract: |
| 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. |
| Key words: software defined radio(SDR),pseudolite receiver,digital platform |
