摘要
PROBLEM TO BE SOLVED: To save energy required for a different radio communication system in a radio communication base station system where a radio information signal is communicated between a central base station provided with a MODEM section whose function can be changed through software and a simple base station mainly consisting of an antenna port, which are interconnected through an optical fiber. SOLUTION: In the radio communication base station system where a plurality of simple base stations 1 each mainly consisting of an antenna port and a central base station 2 that modulates/demodulates radio signals sent/received through antennas of a plurality of the simple base stations and controls channels of them are provided and a radio information signal is communicated through optical fibers between the simple base stations and the central base station, the central base station is provided with a MODEM section 13 employing digital signal processing whose function can be controlled through software and with a control section 14 that varies a frequency conversion amount of the simple base stations and an operating bandwidth of an A/D converter 10 and a D/A converter 18.
