In a DOCSIS based satellite gateway data is transmitted over a single downstream channel, at different throughput rates. Data destined for each subscriber/receiver is assigned a throughput rate depending upon the downstream signal quality of that subscriber/receiver. To accomplish this, the downstream...http://www.google.de/patents/US20040085976?utm_source=gb-gplus-sharePatent US20040085976 - Downstream time domian based adaptive modulation for DOCSIS based applications
