Abstract
A central controller (10) controls the operation of a code division multiple access (CDMA), spread spectrum communication system, which includes base stations (15) and portable transceivers (20) for communicating with the base stations (15). The central controller (10) stores a plurality of seeds, which are used by the portable transceivers (20) in generating pseudo-noise (PN) sequences, and, in response to requests from base stations (15), the central controller (10) distributes at least a portion of the assignable seeds to each of the requesting base stations (15). The base stations (15) that have received seeds from the central controller (10) subsequently transmit the seeds over the air to the portable transceivers (20) within their respective coverage areas. The portable transceivers (20) then utilize the seeds to generate spread spectrum signals for reception by a closest base station (15) having a coverage area in which they are located.
