载频同步
carrier-frequency synchronization
- 但是，一旦多普勒频移超出了锁相环的频率捕捉范围，就无法完成载频同步。
But if the Doppler frequency offset exceed the capture range of PLL, the carrier synchronization will fail. - 调频同步广播系统是具有重叠服务区，使用同一载频和同一节目源，同时同相位广播的调频发射技术。
FM sound sync-broadcasting has overlapped service zone, the same carrier frequency and the source of the program, which can broadcast in-phase at the same time. - 针对载波加权正交频分复用系统中权值选择的不确定性，提出了一种载频盲同步的性能分析方法。
Aiming at the uncertainty of weights selection in the weighting orthogonal frequency division multiplexing system, a performance analysis method for carrier blind synchronization is proposed.
