A system and method for dynamically varying traffic channel sectorization within a spread spectrum communication system is disclosed herein. In a preferred implementation the system is operative to convey information to at least one specified user in a spread spectrum communication system and includes a pseudorandom code generator (50) for generating, at a predetermined chip rate, a pseudorandom noise (PN) signal of a predetermined PN code. The PN signal is then combined with a first information signal in a spread spectrum transmitter (42) to provide a PN spread information signal. The system further includes at least one additional spread spectrum transmitter (44, 46) each for receiving through a respective delay element (52, 54) delayed versions of the PN signal for providing at least one additional modulation signal. A switching transmission network (74) is disposed to selectively transmit via antennas (85, 86) the first and additional modulation signals respectively to a first and at least one additional coverage area. Selective transmission of the first and the at least one additional modulation signal results in variation in size of a first user sector. The first user sector is associated with a first set of traffic channels, one of which is allocated to the specified user. The system may also be configured to selectively receive, and coherently combine, first and second modulation signals from first and second coverage areas. |
