发明名称 METHOD OF AND EQUALIZER FOR EQUALIZING A RADIO FREQUENCY FILTER
摘要 A method (300) of and an equalizer (104-1, 104-2) for equalizing an RF filter (106-1, 106-2) supporting a frequency band by utilizing an antenna calibration path having the RF filter (106-1, 106-2) in a Node B (100) in a TDD system are provided. The method (300) comprises the steps of obtaining (302) an amplitude and phase response of a calibration signal having a frequency in the frequency band, stepwise changing (304) the frequency of the calibration signal, determining (306) a transfer function of the RF filter (106-1, 106-2), and equalizing (308) the RF filter (106-1, 106-2) based on the determined transfer function of the RF filter (106-1, 106-2).
