PROBLEM TO BE SOLVED: To correct a baseband signal according to a transmission channel compensation coefficient and a cable compensation phase.SOLUTION: A device 700 comprises a baseband unit 710, an intermediate frequency/radio frequency (IF/RF) unit 720, and a dual column cross polarization antenna 730. The baseband unit determines compensation coefficients corresponding to four respective transmission channels, determines a cable compensation phase according to a received uplink sounding signal, generates baseband signals for four channels, corrects the base band signals for the four channels according to the compensation coefficients and the cable compensation phase corresponding to the four respective transmission channels, and transmits the baseband signals after the correction to the IF/RF unit. The IF/RF unit transmits the baseband signals after the correction for the four channels to UE via the four transmission channels and the dual column cross polarization antenna.SELECTED DRAWING: Figure 7 |
