Patent number: 8659987Abstract: In one embodiment of a communications network, the predetermined encoding scheme and symbol constellation configurations are chosen so that the range in channel qualities that the encoding scheme and symbol constellation configurations are designed to be utilized within overlap with each other. This overlapping provides hysteresis, which reduces the frequency with which a subscriber must alter encoding scheme and symbol constellations. Reducing the frequency of changing encoding scheme and/or symbol constellation eliminates the communication overhead associated with these changes and increases throughput by enabling the subscriber to spend more time transmitting data.Type: GrantFiled: August 9, 2011Date of Patent: February 25, 2014Assignee: Broadcom CorporationInventor: David L. Hartman, Jr.

Patent number: 7016296Abstract: Methods and systems for communicating on a wireless channel are provided which enable subscribers that share the channel to transmit using different modulation schemes. The modulation scheme used by each subscriber is assigned to the subscriber by a wireless access termination system. The modulation scheme assigned to a subscriber by the wireless access termination system is determined based on measurements of the quality of signals received from that subscriber. In one embodiment, the invention includes a transmitter and a receiver. The receiver is capable of transmitting data using one of a number of encoding and symbol constellation configurations. The receiver is also capable of receiving a first signal. Receiving the first signal causes the transmitter to transmit a second signal using a specified encoding and symbol constellation configuration.Type: GrantFiled: May 15, 2001Date of Patent: March 21, 2006Assignee: Broadcom CorporationInventor: David L. Hartman, Jr.
