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 signal transmission and virtual site locations in the cell, rather than at the center of the cell. A receiver includes multiple antennas using spatial diversity, such as beamforming and cancellation, to extract the desired signal.
