Abstract:
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.
