Patent number: 8773986Abstract: A system and method for providing upstream adaptive modulation. Burst parameters associated with a range of data interval usage codes (IUCs) are defined. Each of the data IUCs has a different modulation order and forward error correction (FEC). The SNR and codeword error rate for each satellite modem in the network are monitored. The data IUCs are dynamically assigned to different satellite modems within an upstream channel based on SNR and/or codeword error rate to enable each of the satellite modems in the upstream channel to achieve maximum bandwidth efficiency during upstream data transmissions. Bandwidth requests are received from the satellite modems and granted. The grant includes the assigned data IUC. The data bursts received in the upstream channel are each processed using the parameters from the assigned IUC for each of the satellite modems sending data in the upstream channel.Type: GrantFiled: December 28, 2010Date of Patent: July 8, 2014Assignee: Broadcom CorporationInventors: Mark Dale, David L. Hartman, Dorothy D. Lin, Rocco J. Brescia, Jr., Alan Gin, Ravi Bhaskaran, Jen-chieh Chien, Adel Fanous

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: 8300657Abstract: A modified ranging request in a broadband communications system. The modified ranging request includes a header, a management message header attached to the header, a management message payload attached to the management message header, and a CRC attached to the management message payload. The management message header enables bandwidth requests to be made by subscriber equipment without contention. The management message header also includes state of health information on the status of a downstream transmission for enabling a central location to determine how to assign subscribers to queues in an adaptive modulation scheme.Type: GrantFiled: April 12, 2010Date of Patent: October 30, 2012Assignee: Broadcom CorporationInventors: Mark R. Dale, David L. Hartman, Alan Gin, Jen-chieh Chien, Anders Hebsgaard, Rocco J. Brescia, Jr., Cho-Hsin J. Wang, Alan Y. Kwentus, Dorothy D. Lin

Patent number: 8010882Abstract: Methods and systems for modifying DOCSIS-based transmission paths for communication in higher frequency and/or wireless environments, such as wireless terrestrial communication systems and satellite communication systems. An inner turbo-code is combined with a DOCSIS based Reed-Solomon (“RS”) forward error correction (“FEC”) coding scheme, to produce a concatenated turbo-RS code (other FEC codes can be utilized). In phase and quadrature phase (“I-Q”) processing is utilized to enable relatively low cost up-converter implementations. The I-Q processing is preferably performed at baseband, essentially pre-compensating for analog variations in the transmit path. Power amplifier on/off control capable of controlling on/off RF power control of remote transmitters is modulated on a transmit cable to reduce the need for a separate cable.Type: GrantFiled: April 5, 2010Date of Patent: August 30, 2011Assignee: Broadcom CorporationInventors: Mark Dale, Dorothy Lin, Jen-chieh Chien, Alan Gin, Rocco J.
