| Abstract: |
| The design of a TDRSS S - band consumer terminal is described, and such key techniques as adaptive PN code capturing, digital coherent transponding under the condition of low SNR and large dynamic range are analyzed. Finally, the performance of the device is compared with these of its kind abroad. |
