capture carrier的意思|示意

In the light of these characteristics, the paper deduces the cyclic spectrum of UQPSK, and puts forward an algorithm for carrier-frequency capture based on cyclostationarity.

针对这一特性，文中给出了UQPS K信号的循环谱，提出了基于循环平稳特性的载频获取算法。

But if the Doppler frequency offset exceed the capture range 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。

It directly processes the phase of the received signal and realize fast capture of the carrier frequency and keeping the carrier phase.

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。

From the point of view of theory, motion capture data is a new type of information carrier, so it is necessary to research on data capturing, processing, analysis, storing, browsing and transferring.

在理论方面，运动捕捉记录下的数据是一种新的信息载体，因此在数据的获取、处理、分析、存储、检索、传输都有必要进行深入研究。

In this paper, a novel frequency synchronization estimation algorithm is provided to achieve carrier frequency capture and tracking.

文中提出了一种低复杂度的同步估计，来实现载波频率捕获和跟踪。

It has been proved that an improved FFT frequency correction technology, which makes carrier frequency deviation come into fast capture bandwidth quickly, is presented to correct frequency.

实践表明：利用一种改进的FFT校频技术对载波频偏进行一次校频，能使载波频偏快速落入锁相环快捕带内。
