| Abstract: | The frequency weeping algorithm and decision-directed of reduced constellation (RC-DD) algorithm are together used in QAM carrier recovery. And then, the basic theory and structure of carrier recovery algorithm are introduced. The simulation resulsts show that the proposed method has reliable performance, quick capture speed, good stability and high precision, and the capture frequency offset can reach the level of symbolic rate. |
