摘　　要：介绍一种新型的全数字化载波恢复环，用来直接从ＭＰＳＫ或ＮＱＡＭ信号中提取同步的载波信号．由于实现了全数字的环路，这种环路将具有高度的稳定性、简洁性．实验结果表明环路具有良好的载波恢复性能和很小的相位抖动．In this paper, a new all-digital carrier recovery loop is discussed,which can extract synchronous camer signals from MPSK and NQAM signals.Owing to the results of all-digitized loop, the new loop will be of high stability and compactness. The experimental results show that the new loop has good behaviors on the carrier recovery property and small phase jittering.
