time and frequency synchronization

基本解释

This dissertation investigates the topic of time and frequency synchronization for OFDM and MIMO-OFDM systems.
准确的时间同步和精确的频率同步是OFDM系统和MIMO OFDM系统正常工作的前提。
However OFDM and MIMO OFDM systems are very sensitive to time and frequency synchronization errors, especially the frequency synchronization error.
但OFDM系统和MIMO OFDM系统对时间和频率同步误差很敏感，特别是频率同步误差。
A new time and frequency synchronization method based on frequency domain correlation for an Orthogonal Frequency Division Multiplexing (OFDM) system is presented.
该文根据频域相关的原理，提出了一种新的用于无线移动信道下的正交频分复用（OFDM）系统的时频同步算法。
