Method and device for compensating frequency response of a filter unit in remote radio unit in real time

摘要

A method for compensating frequency response of a filter unit in remote radio unit in real time, said remote radio unit comprises filter unit equalizer, transmitter observation receiver and antenna calibration receiver, said method comprising the steps of: receiving input signal of said filter unit by transmitter observation receiver; receiving output signal of said filter unit by antenna calibration receiver; calculating coefficients of filter unit equalizer in real time based on said input signal and said output signal; updating said filter unit equalizer based on said calculated coefficients in order to compensate frequency response of said filter unit. A device to carry out the above method, remote radio unit comprising said device and a telecommunication system comprising said remote radio unit are also provided.

1. A method for compensating a frequency response of a filter unit in a remote radio unit in real time, the remote radio unit comprising a filter unit equalizer, a transmitter observation receiver, and an antenna calibration receiver, the method comprising:
receiving an input signal of the filter unit at the transmitter observation receiver; filtering the input signal at the filter unit to produce a filtered output signal; receiving the filtered output signal at the antenna calibration receiver; calculating coefficients of the filter unit equalizer in real time based on the input signal and the filtered output signal; and updating the filter unit equalizer based on the calculated coefficients in order to compensate the frequency response of the filter unit.
