摘要： 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.

摘要： 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.

摘要： 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. When any of the satellite modems' SNR and/or codeword error rate changes, the data IUC for that satellite modem is changed accordingly.

摘要： 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.

摘要： A system and method for minimizing the frequency error of satellite modem signals at a satellite gateway. The gateway downstream baud (symbol) clock and the elements that control the upstream frequency (i.e., local oscillators in the conversion chain, A/D sample clocks) are locked to a common frequency reference. The gateway sends upstream satellite frequency offset information, such as satellite ephemeris data from which to calculate Doppler offset, to the satellite modem. The satellite modem locks the frequency of the satellite modems master oscillator to the recovered baud rate using a frequency locked loop. The satellite modem uses its master oscillator as the carrier reference for the upstream frequency up conversion. The satellite modem uses or calculates the upstream satellite frequency offset and compensates for this offset by shifting its center frequency.
