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.

Abstract: The invention relates to a communication system in which transmission takes place according to a format which permits different types of data to be combined and transmitted within a single transmission. The novel feature is that the communication system transmits variable length frames of data in packets, and that a data combining and transmission sub-system (14, 16, 18, 20) is provided so that when a frame of data does not require a complete packet for transmission, the data combining sub-system combines the frame of data with additional data to provide a complete packet. The data combining sub-system comprises input means for receiving the frame of data and the additional data and for combining the frame of data and the additional data to provide a complete packet responsive to a control signal, and control means for providing the control signal.
