摘要： A method and system for channel tracking in an adaptive equalizer for a digital data receiver. The method includes determining a first set of tap weights and a second set of tap weights of the equalizer, and determining a difference between the first and second sets of tap weights. The method also includes determining an error estimate based on symbols received at the receiver, comparing the error estimate with a divergence threshold, and determining a step size factor based on the difference and the comparison.

摘要： Embodiments of the invention relate to systems and methods for tracking phase in a receiver which uses multiple phase tracking techniques. A phase tracking module generates a plurality of symbol decisions related to received 8-level-vestigial-sideband (“8VSB”) signals, determines a phase tracking threshold value based on a mean square error, receives an estimated imaginary component of a transmitted signal based on the symbol decisions, and determines a phase estimate based on the imaginary component of the transmitted signal and the plurality of symbol decisions. The phase tracking module selects one of a first phase tracking technique and a second phase tracking technique based on the phase estimate. The first phase tracking technique is selected when the phase estimate is greater than the phase tracking threshold value, and the second phase tracking technique is selected when the phase estimate is less than the phase tracking threshold value.

摘要： A method and system for determining a step size of an adaptive equalizer for a digital data receiver. The data received by the receiver includes coded symbols and uncoded symbols. The method includes determining a first error estimate based on decoded symbols corresponding to the coded symbols, determining a second error estimate based on the uncoded symbols, adaptively selecting the first error estimate or the second error estimate based on a convergence criterion, and determining a step size based on the selected error estimate.
