A TDMA receiving apparatus for use with a base station is disclosed, that comprises a plurality of receiving antennas, a plurality of outdoor units for converting received signals into first intermediate frequency signals, a plurality of unit connecting cables for sending the intermediate frequency signals, and an indoor unit for obtaining demodulated signals from the intermediate frequency signals. The indoor unit has a plurality of second frequency converters for converting the first intermediate frequency signals into second intermediate frequency signals with the same frequency and a power combining unit for combining the powers of the second intermediate frequency signals. The combined intermediate frequency signal is demodulated by a common demodulating circuit. <IMAGE> |
