| 摘 要： | 针对数字信号传输同步接收机的数字化实现，提出一种载波同步新算法即相位处理载波恢复算法。它直接对接收信号的相角进行处理，完成载波频率的快速捕获和载波相位跟踪。理论分析和计算机仿真表明，该算法简单有效，运算量小，便于用DSP器件来实现，适用性强。

| Abstract: | Aiming at the digital implementation of the synchronous receiver of digital signal transmission, a new carrier synchronization algorithm, namely a carrier recovery algorithm with phase processing is proposed. It directly processes the phase angle of the received signal and realizes the fast capturing of the carrier frequency and the tracking of the carrier phase. Results of analysis and simulation show that the algorithm is simple, efficient and very suited to DSP implementation. |
