Patent number: 8098606Abstract: A method, apparatus and computer program product for generating and processing upstream channel descriptor (UCD) messages in a DOCSIS-based broadband communications system, such as a DOCSIS-based two-way satellite communications system, is provided. A satellite modem termination system (SMTS) generates a UCD message that includes one or more standard parameters pertaining to an upstream channel of the two-way satellite communications system, wherein the one or more standard parameters are defined in accordance with the DOCSIS protocol, and one or more satellite application-specific parameters pertaining to the upstream channel, wherein the one or more satellite application specific parameters are not provided for by the DOCSIS protocol. The UCD message is transmitted to a satellite modem that extracts both the standard and satellite application-specific parameters for use in managing communication over the upstream channel.Type: GrantFiled: April 23, 2003Date of Patent: January 17, 2012Assignee: Broadcom CorporationInventors: Mark Dale, David Hartman, Dorothy Lin, Rocco Brescia, Alan Gin, Ravi Bhaskaran, Jen-chieh Chien, Adel Fanous

Publication number: 20110274151Abstract: 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: ApplicationFiled: December 28, 2010Publication date: November 10, 2011Applicant: Broadcom CorporationInventors: Mark DALE, David L.

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.

Publication number: 20100279599Abstract: A downstream adaptive modulation system and method. The downstream adaptive modulation system comprises a wireless access termination system and one or more wireless modems. The wireless access termination system includes a plurality of queues and a parser. The parser parses data traffic onto the plurality of queues. Each queue is associated with a different coding and modulation scheme. Each of the one or more wireless modems receives data traffic from the plurality of queues based on the wireless modem's ability to demodulate and decode the signal from each of the plurality of queues. When a wireless modem experiences a change in signal strength, the present invention enables the wireless modem to adapt to data from other queues to compensate for the change in signal strength. Thus, if the signal strength improves over a period of time, the wireless modem may receive data at a higher order modulation and FEC code rate.Type: ApplicationFiled: July 12, 2010Publication date: November 4, 2010Applicant: Broadcom CorporationInventors: Mark Dale, David Hartman, Anders Hebsgaard

Publication number: 20100074167Abstract: 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 DOCSIS MAC data is parsed to extract DOCSIS packets. The DOCSIS packets are then loaded into packet queues based on an identifier within such packets such as the MAC destination address or SID. Each of the queues represents a bandwidth efficiency or throughput rate that can be currently tolerated by specific subscribers based on the current signal quality being experienced at the subscriber location. A PHY-MAP describing the downstream data structure to be transmitted and inserted into the downstream data. Data is extracted from the packet queues in queue blocks as defined by the PHY-MAP.Type: ApplicationFiled: March 23, 2009Publication date: March 25, 2010Applicant: Broadcom CorporationInventors: Mark Dale, Anders Hebsgaard, David Hartman, Alan Kwentus, Steven Jaffe, Kelly Cameron, Stephen Krafft, Alan Gin, Jen-chieh (Jack) Chien, Dorothy Lin, Rocco Brescia, Joyce Wang

Patent number: 7606188Abstract: Satellite communications are carried out using the Data Over Cable Interface Specification (DOCSIS). Satellite modems are notified of upstream channel congestion by inserting a congestion notification message in a medium access protocol (MAP) message for the upstream channel. Specifically, the congestion notification message is inserted in an unused field of the MAP message, such as the explicit congestion notification (ECN) field. The MAP message can also carry other characteristics of the upstream channel, including priority threshold, multicast access burst availability, and available bandwidth.Type: GrantFiled: December 5, 2006Date of Patent: October 20, 2009Assignee: Broadcom CorporationInventors: Mark Dale, David Hartman, Dorothy Lin, Rocco Brescia, Alan Gin, Ravi Bhaskaran, Jen-chieh Chien, Adel Fanous
