Time delay detection method and device of antenna calibration link

天线校准链路的时延检测方法及装置

Abstract

The invention provides a time delay detection method and a device of an antenna calibration link. The time delay detection method of the antenna calibration link comprises producing a training sequence by a transmitting branch and receiving a receiving sequence corresponding to the training sequence by a receiving branch; calculating to obtain a first delay value according to the cross-correlation function of the training sequence and the receiving sequence; calculating to obtain a second delay value according to the unit impulse response calculated from the training sequence and the receiving sequence; and calculating an intermediate frequency channel delay and an antenna feeder part delay according to the first delay value and the second delay value. The time delay detection method and the device of the antenna calibration link have the advantages of being capable of obtaining the intermediate frequency channel delay and the antenna feeder part delay respectively, being accurate in detection result, without needing the artificial participation, saving the manpower and improving the efficiency.
本发明提供一种天线校准链路的时延检测方法及装置。其中方法包括:由发射支路产生训练序列并由接收支路接收与该训练序列对应的接收序列;根据所述训练序列与所述接收序列的互相关函数计算得到第一时延值;根据所述训练序列与所述接收序列计算得到的单位冲激响应计算得到第二时延值;根据所述第一时延值及所述第二时延值计算得到所述中频通道时延和所述天馈部分时延。本发明可以分别得到中频通道时延和天馈部分时延,检测结果更加准确,并且无需人工参与,节省了人力,提高了效率。
