Abstract
A communication system includes a hub station and a plurality of terminal stations. An inbound satellite communication link from each of the terminal stations to the hub station sends digital data packets encoded with a CDMA code for code division multiple access during synchronized time slots on a contention channel. Each of the digital data packets is encoded with the same CDMA code during a first transmission, but each packet is encoded with an alternate CDMA code during any subsequent transmission.
