A feasible scheme using PAL TV signal for proceeding active time and frequency transfer and synchronization is described in this paper.

本文介绍了利用PAL制电视信号进行有源电视时间频率传递与同步的一种可行的方案。

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。

Triggering time synchronization error model is derived, and based on phase noise model of frequency source, random synchronization error is considered.

本文建立了触发时间同步误差模型，结合频率源相位噪声模型，初步分析了随机型时间同步误差对成像的影响。
