  • Patent number: 8098719
    Abstract: A method for initializing modems in a multicarrier transmission system to establish a communication link between the transmitter and the receiver. An exemplary embodiment includes the steps of providing a predetermined parameter value that approximates a corresponding actual parameter value of the communication link, establishing a data communication link between a first transceiver and a second transceiver using the predetermined parameter value to allow the transmission of data, determining the actual parameter value, and seamlessly increasing the data rate of the established data communication link by using the determined actual parameter value to provide an steady state communication link with an updated data rate.

  • Patent number: 8095863
    Abstract: An improved decoder and decoding method for low density parity check (LDPC) codes is provided. Decoding proceeds by repetitive message passing from a set of variable nodes to a set of check nodes, and from the check nodes back to the variable nodes. The variable node output messages include a “best guess” as to the relevant bit value, along with a weight giving the confidence in the, guess. The check node output messages have magnitudes selected from a predetermined set including neutral, weak, medium and strong magnitudes. The check node output messages tend to reinforce the status quo of the input variable nodes if the check node parity check is satisfied, and tend to flip bits in the input variable nodes if the check node parity check is not satisfied. The variable node message weights are used to determine the check node message magnitudes.

  • Publication number: 20120002709
    Abstract: A modem for use in Digital Subscriber Line communications transmits and receives data over the local subscriber loop in common with voice information over the loop, while avoiding the need for voice/data splitters. The modem responds to disruptions associated with “disturbance events” such as on-hook to off-hook transitions and the like by rapidly switching between pre-stored channel parameter control sets defining communications over the loop under varying conditions. In addition to changing parameter control sets responsive to a disturbance event, the modem may also change transmission power levels and other system parameters such as frequency domain equalizer characteristics. Further, provisions are made for reduced bandwidth communications under selected conditions.

  • Patent number: 8077767
    Abstract: An adaptive transversal filter having tap weights Wj which are products of corresponding tap coefficients Cj and tap gains Mj is provided. A filter control loop controls all of the tap coefficients Cj such that an error signal derived from the filter output is minimized. One or more tap control loops controls a tap gain Mk such that the corresponding tap coefficient Ck satisfies a predetermined control condition. For example, |Ck| can be maximized subject to a constraint |Ck|?Cmax, where Cmax is a predetermined maximum coefficient value. In this manner, the effect of quantization noise on the coefficients Cj can be reduced. Multiple tap control loops can be employed, one for each tap. Alternatively, a single tap control loop can be used to control multiple taps by time interleaving.

  • Patent number: 8045603
    Abstract: A transceiver and method for communicating over a communications channel having a plurality of subchannels are described. In particular, the transceiver is capable of dynamically switching between communicating data for a first active application set and communicating data for a second different active application set. An active application set is defined as the set of one or more active applications for which the transceiver is currently communicating data. As part of communicating data for the first active application set, the transceiver allocates the subchannels to the one or more applications in the first application set. The transmission requirements of the first active application set defines a first communication state of the transceiver. When the transceiver dynamically transitions to communicating data for the second different application set, the transceiver reallocates the subchannels to the one or more applications in the second different application set.

  • Patent number: 8041360
    Abstract: A scheme that enables seamless roaming between the WLAN and the cellular carrier network by enabling a user that originates a call in the WLAN and happens to go outside the range of the WLAN to automatically switch over to the cellular carrier network without losing connection with the other party. This solution assumes that the mobile device has the capability to operate in at least two modes that include the WLAN mode and one of the cellular carrier modes, such as the GSM, IS-95 CDMA, IS-136 TDMA, and iDEN.

  • Patent number: 7999708
    Abstract: A method of phase mismatch correction in high-sample rate time-interleaved analog-to-digital converters (ADC) is provided. An ADC parallel array has an output signal that is processed by a phase-mismatch detector. The detector drives a clock generator control circuit for the ADC array. The clock generator includes a common mode logic (CML) buffer, a CMOS, a non-overlapping generator, a DAC and a decimating low-pass filter. The CML receives a reference clock signal providing source line control (SLC) to the CMOS, the CMOS provides SLC to the DAC that is controlled by the filter which receives a digital control signal from the phase mismatch detector. The DAC provides a corrected timing input to the CMOS that provides the corrected timing signal to the non-overlap generator, where a delay in the clock path is modified and the signal path is unaltered.

  • Publication number: 20110193536
    Abstract: A method of identifying and correcting each of the changes that may occur with wire pairs between the transmitter and receiver in Ethernet 10GBase-T cabling is provided. The method includes four wire pairs A, B, C and D, a polarity swapping and scrambler state machine that determine if the chosen pair matches the requirements for pair A. A slave Tap state machine generates a rule for correct B, C and D patterns based on a pair chosen as pair A. The cables B, C and D are iteratively swapped to rearrange the pair mapping into the polarity swap state machine, and a deskew state machine identifies the latency difference between the different pairs. If the rules are not satisfied, a new pair A is designated at the swapping state machine and the process is repeated until the rules are satisfied.

  • Publication number: 20110141875
    Abstract: Combined echo and crosstalk cancellation is provided. Frequency domain adaptive filters are used to remove or reduce the effects of echo and crosstalk for a multi-channel and full-duplex communications system. Data from each transmit channel is buffered and converted to the frequency domain. The frequency domain data is multiplied by crosstalk coefficients to obtain a frequency domain correction signal for each channel. Adaptation of the crosstalk coefficients is based on correlations between the error signals and the data from each of the transmit channels. A single frequency domain transform engine, such as a Fast Fourier Transform engine, is employed for all calculations to save power and area.

  • Patent number: 7952447
    Abstract: An adaptive electromagnetic interference (EMI) detection and reduction device for multi-port applications is provided. The invention includes at least two physical devices (PHY), where the PHYs transmit data along wire pairs to a register jack (RJ). The transmissions create EMI along the wire pairs, where the transmissions have constructively interfering resonant frequencies having phases and amplitudes. An antenna is disposed proximal to each RJ, where the antennae detect each frequency. A resonating network determines a peak amplitude of each frequency, an envelope detector amplifies each peak amplitude from the resonating network. A discretization circuit converts the amplified peak to discrete amplitude values, where the discretization circuit transmits the discrete amplitude values to a controller.

  • Patent number: 7936223
    Abstract: A low spur phase-locked loop (PLL) architecture is provided. A frequency-synthesizing PLL that includes a differential Kvco gain linearization circuit with adjustable DC offset is used to reduce clock jitter. The free-running oscillation frequency of the VCO of the PLL is centered near the desired frequency using programmable loads to minimize the required control voltage range. The PLL uses a differential architecture that includes a charge pump that compensates for variations in Kvco and a LC tank oscillator with differential controlled varactor. The differential PLL architecture demonstrates that the reference spur can be well controlled to below ?80 dBc.
