Abstract
In a cellular communication network, capacity in a cell is increased by placing antennas transmitting different signals on the same carrier frequency at separated locations in the cell, rather than at the center of the cell. A receiver includes multiple antennas and uses spatial diversity, such as beamforming and cancellation, to extract the desired signal.
