  • Systems and methods for multicarrier modulation using multi-tap frequency-domain equalizer and decision feedback
    Patent number: 7656976
    Abstract: Through the use of feedback in determining frequency domain equalization, intersymbol interference can be reduced. Specifically, the determined constellation point closest to the determined received point can be fed back to aid in determining one or more other closest constellation points.
    Type: Grant

    Date of Patent: February 2, 2010

  • Systems and methods that provide frequency domain supplemental training of the time domain equalizer for DMT
    Patent number: 7636389
    Abstract: Using a known or later developed time domain equalizer coefficient training algorithm, a least square solution for the time domain equalizer coefficients is taken at a starting point and iteratively improved on. In particular, the improvement is directed towards maximizing number of bits per frame loaded over the time domain equalizer coefficient choice. This can be accomplished by maximizing capacity directly rather than setting a goal to shorten the channel and hoping that the capacity will be maximized as a result.

  • Systems and methods for LDPC coded modulation
    Publication number: 20090183048
    Abstract: Typical forward error correction methods employ Trellis Code Modulation. By substituting low density parity check coding in place of the convolution code as part of a combined modulation and encoding procedure, low density parity check coding and modulation can be performed. The low density parity check codes have no error floor, no cycles, an equal bit error rate for the information bits and the parity bits, and timely construction of both a parity check matrix with variable codeword size and a generator matrix is possible.

  • Systems and methods for implementing receiver transparent Q-mode
    Patent number: 7558329
    Abstract: In a receiver transparent Q-mode, i.e., a Q-mode that is only implemented by a transmitter, the receiver is unaware of the Q-mode state of the transmitter. In this type of Q-mode configuration, the transmitter could enter and exit Q-mode as desired while the receiver, could, for example, continue to function as if operating normally, such as in “showtime.” Through this approach, it is not necessary for the receiver to detect the transmitter's entry and exit of Q-mode.

  • Beaulieu series approach to optimal UMTS RACH preamble detection estimation
    Patent number: 7394875
    Abstract: A method for preamble detection in mobile unit to base unit wireless telephony sets a preamble detection threshold based upon a Beaulieu series computation dependent upon preamble correlation data. This preamble detection threshold adjusts for noise by assuming the noise is additive White Gaussian noise (AWGN) with a known variance. The method determines the threshold for achieving a probability of false detection of the preamble from noise input of less than 0.001.

  • MULTI-TAP FREQUENCY DOMAIN EQUALIZATION WITH DECISION FEEDBACK AND TRELLIS DECODING
    Publication number: 20070211812
    Abstract: An input estimator is based on a combined MFDQ-DF and trellis for use in, for example, an ADSL environment. In particular, for an ADSL implementation, the system will have one feedback tap for the decision feedback. However, it should be appreciated that the idea and basic concept of using the structure of a trellis to aid in determining the feedback point can be extended to any system using a feedback equalizer to estimate input to a trellis decoder.
