ABSTRACT:
In a cellular mobile communication system, a number of transmit/receive units are respectively connected to antenna sites for conversion of signals between a radio frequency and a baseband frequency and a number of modulator/demodulator units is provided. Control circuitry receives signals from the modulator/demodulator units indicating strengths of signals received by the antennas and controls a switcher for establishing connections between the transmit/receive units and the modulator/demodulator units. Control circuit further controls a combining circuit to combine the signals associated with at least two of the modulator/demodulator units during an intra-cell handover.
