A power pooling apparatus uniformly distributes sector loads in a mobile communication system. The power pooling apparatus comprises a distributor for distributing signals output from a signal generator according to respective sectors; a radio signal processor for performing signal processing to provide an output of the distributor to an antenna; and an adaptive signal processor for determining a characteristic matrix of the distributor by using an output in a predetermined position on a signal processing path of the radio signal processor, and providing the characteristic matrix of the distributor to the distributor.
