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.

Patent number: 8565321Abstract: Provided are a method and system for processing at least two consecutive MPEG Q-blocks in a communications system, one of the Q-blocks being low rate and the other being high rate. The method includes back-filling an empty portion in a first transmitted Q-block with a first portion of second type data, the remaining portion of data of the second type data being included in another Q-block prior to transmission. The second type data crosses a boundary between the first and the other Q-block when the actual number is less than a corresponding maximum number. Finally, the method includes receiving within an associated subscriber modem one of the first and the second type data and not receiving the other of the first and the second type data when the second type data crosses the boundary.Type: GrantFiled: March 29, 2005Date of Patent: October 22, 2013Assignee: Broadcom CorporationInventors: Alan Gin, Jen-Chieh Chien

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

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.

Patent number: 7992174Abstract: Provided are a method and system for determining system time in a satellite based cable data communication system. The system includes a satellite modem termination system configured to transmit data frames to a receiver in a predetermined symbol rate. Each frame includes a corresponding number of symbols and has a time stamp (i) indicative of the frame's time of transmission and (ii) positioned within the frame at a location common to all of the frames. The method includes receiving at least two consecutively transmitted data frames within the receiver and registering the time stamp of the first received data frame within the receiver to produce a first time stamp. Also, the time stamp of the second received data frame is registered within the receiver to produce a second time stamp. The time of transmission of the second transmitted data frame is updated, wherein the updating is a function of the first time stamp, the second time stamp, the corresponding number of symbols, and the symbol rate.Type: GrantFiled: March 29, 2005Date of Patent: August 2, 2011Assignee: Broadcom CorporationInventors: Alan Gin, Jen-Chieh Chien

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
