ABSTRACT:
In a wireless base station comprising a center unit, and a remote unit provided with an array antenna and connected to the center unit through an optical fiber, the center unit outputs to the optical fiber a transmission signal in a base band state prior to array processing, the remote unit performs the array processing of transmission signals in accordance with array weights and converts the transmission signals into RF signals, thereby to localize the compensation for transmission signal deviations occurring among the antenna elements on the remote unit side.
