Patent number: 8654695Abstract: A method and apparatus of link adaptation of a broadcast system is disclosed. The method includes a base station adaptively determining a signal quality threshold. The base station broadcasts a signal, wherein the signal includes the signal quality threshold. A plurality of subscribers receives the signal, and measure a signal quality. Each of a subset of the plurality of subscribers transmits back to the base station an indicator of whether the received signal has a measured signal quality that is either above or below the signal quality threshold. A percentage of subscribers that receive the signal having a received signal quality above the signal quality threshold is estimated. A transmission modulation format and coding is selected based on the estimated percentage.Type: GrantFiled: December 14, 2007Date of Patent: February 18, 2014Assignee: Broadcom CorporationInventors: Louay Jalloul, Sriram Mudulodu, Djordje Tujkovic, Kamesh Medepalli
