针对全数字接收机，即数字信号传输同步接收机的数字化实现，本文提出了一种载波同步新算法——相位处理载波恢复法。它直接对接收信号的相角进行处理，以完成载波频率的快速捕获和载波相位的跟踪。理论分析和计算机模拟表明，这种算法简单而有效，运算量非常小，便于用ＤＳＰ甚至单片微机来实现，适用性强。 Aiming at the digital realization of all-digital receiver, ie digital signal transmission synchronous receiver, this paper proposes a new carrier synchronization algorithm-phase-processing carrier recovery method. It directly to the phase angle of the received signal processing to complete the fast acquisition of carrier frequency and carrier phase tracking. Theoretical analysis and computer simulation show that this algorithm is simple and effective, the computation is very small, easy to use DSP or even single-chip microcomputer to achieve, applicability.
