摘要： PROBLEM TO BE SOLVED: To provide a method for allowing compensation of frequency errors associated with asynchronous oscillators in multiple remote base stations.SOLUTION: A base station apparatus for a wireless communication system in which multiple base stations connected to a control station via a wired line or the like connects to subordinate terminal stations via wireless lines of the same frequency and converts between a digital signal and an analog signal of a radio frequency between the control station and the terminal stations comprises: a first oscillator for supplying a clock signal necessary for conversion between a digital signal and an analog signal; reference timing obtaining means for obtaining a reference clock or the like on wire from signals commonly received by multiple base stations; frequency error estimation means for estimating a frequency error of the first oscillator by comparing a clock signal from the first oscillator with the reference clock or the like; and frequency error compensation means for performing signal processing to cancel the frequency error estimated by the frequency error estimation means on a digital signal.

摘要： PROBLEM TO BE SOLVED: To provide a diversity communication system which can reduce the number of reception systems in a centralized base station, realize simplification of device configuration and low cost, and achieve higher communication quality. SOLUTION: A centralized base station 10 is configured to control a plurality of remote base stations 40 in such a way only selected remote base stations 40 transmit an optical signal, to combine, before detection, received multiple optical signals, and to perform demodulation processing by converting a combined optical signal into an electrical signal. The plurality of remote base stations 40 comprise control means for turning on or off transmission of an optical signal. The centralized base station 10 comprises control means which measures reception power of an optical signal combined before detection regarding all combinations selecting two or more remote base stations out of the plurality of remote base stations 40, selects a combination of remote base stations 40 whose reception power becomes the largest, and controls the plurality of remote base station 40 in such a way only the selected remote base stations 40 transmit an optical signal.
