| () |
| Abstract: |
| Expressions of tracking error caused by random noise are deduced,combining with the theory of a DSSS(Direct Sequence Spectrum Spreading) tacking receiver.According to the formulas presented,the influence of radom noise on tacking precision is analyzed.Both advantages and disadvantages of all the error voltage extraction methods mentioned are compared.The application value of the formulas is designated. |
| Key words: DSSS,tracking receiver,error voltage extracting,noise error, |
