| Abstract: |
| This paper gives the noise in RF front end of a satellite navigation receiver employing concept of noise - temperature and analyses the noise resulting from A/D converter and unsynchronization of PN code. All the technical specifications of designed receiver have achieved advanced level which proves the validity and rationality of conclusions. |
| Key words: satellite navigation receiver SNR A/D converter noise coefficient software radio |
