A code division multiplexing system for a link between components of a satellite communications system is disclosed where, using spread spectrum techniques, channel blocks are each spread by a pre-assigned orthogonal chip-coded waveform. The pre-assigned orthogonal chip-coded waveforms are each preferably...http://www.google.de/patents/US7180873?utm_source=gb-gplus-sharePatent US7180873 - Spread spectrum code division destination access (SS-CDDA) for satellite communication system with distributed gateways
