|
| () |
| Abstract: |
| A demodulator is presented in this paper, which is capable of receiving the payload data from both TERRA and AQUA. Analysis is made on the carrier recovery loop and timing recovery loop to process both UQPSK signals and SQPSK signals, and the circuit design is introduced.Now,the receiver is used by receiving stations. |
