But if the Doppler frequency offset exceed the capturerange of PLL, the carrier synchronization will fail.
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。
2
Experimental results demonstrate that it is characteristic of wide capturerange, short capture time and satisfactory performance under noisy environment.
实验结果表明,它具有捕捉范围宽、捕捉时间短和在噪声背景下有令人满意的性能等特点。

Compared with conventional PLL threshold extended demodulator, it features wider capturerange, shorter capture time and significant improvement in threshold level.
