<p>A method and system of forming and processing communication links in a satellite communications system (10). The satellite communications system includes a plurality of groups of transmitters, a satellite and a plurality of destination receivers. Each transmitter is associated with only one transmitter group and transmits a communications signal. Each respective communications signal is a CDMA signal having a predetermined code that is associated with a transmitter. Each respective predetermined code is selected from a code set assigned to the group of transmitters with which the transmitter is grouped. Each code set is different from code sets associated with the transmitters of other selected transmitter groups so that the code sets are arranged in a code set pattern that is repeated for selected groups of transmitters. The satellite receives the communications signals and groups together each received communications signal having a same predetermined code set. The code sets of selected uplink communications signals in a group of received communications signals are fully or partially despread, filtered, and respread so that the group of communications signals contains communications signals from only one code set. Each group of communications signals is then transmitted to a different destination receiver, or groups on different code sets to the same destination receiver. <IMAGE></p> |
