Abstract

PROBLEM TO BE SOLVED: To provide a received data repeating circuit for CDMA base station by which the number of wirings between a receiving part and a baseband processing part in the case of repeating baseband received data from the radio receiving part to the baseband processing part can be reduced in the base station of a mobile communication network in a CDMA system. SOLUTION: In radio receiving parts 10a-10d of this received data repeating circuit, signals received by respective antennas are demodulated/frequency converted by demodulating parts 11a-11d, A/D converted by A/D converting parts 12a-12d, outputted as baseband received data and inputted to an output data converting part 21, any arbitrary received data are selected, multiplexed in time dividing manner and inputted to an input data converting part 31 later, multiplexed received data are demultiplexed and the demultiplexed baseband received data are inputted to an inverse spread processing part 32.
