Abstract:
Radio base station equipment is connected to radio transmitting/receiving equipment provided in sectors (S), into which a communication area is divided, by an optical fiber (30), and performs radio communication with mobile terminals located in the respective sectors (S) via the radio transmitting/receiving equipment wherein a delay processing section delays a signal for each sector (S) according to a delay correction value obtained by subtracting a delay amount in each sector (S) from a maximum delay amount of a delay amount measured for each sector (S) and a baseband processing section obtains the signal from each sector (S) delayed by the delay processing section by setting a reception window at a position corresponding to the maximum delay amount.
