Abstract: Collisions between messages simultaneously transmitted by multiple spread spectrum transmitters are reduced by distributing the transmissions over the available resources of the receiver. Each mobile station uses one or more randomization methods to distribute its transmissions. Each mobile station includes a microprocessor (100); an encoder (140); a timing generator (136); a PN long code sequence generator (146); and XOR gate (152). The system is used in a CDMA mobile telephone system.
