Abstract
An update mechanism and approach are provided for configuring a communications receiver. According to the approach, a time domain equalizer and a frequency domain equalizer in a communications receiver are dynamically updated based upon performance data that indicates the performance of a communications channel from which the communications receiver receives data. This approach accounts for changes in the communications channel attributable to changes in the transmission medium or changes in interference sources.
Claims36
A communications receiver comprising:
- a time domain equalizer;
- a frequency domain equalizer;
- and
- an update mechanism configured to update both the time domain equalizer and the frequency domain equalizer based upon performance data that indicates performance of a communications channel from which the communications receiver receives data.
An update mechanism configured to update both a time domain equalizer and a frequency domain equalizer in a communications receiver based upon performance data that indicates performance of a communications channel from which the communications receiver receives data.
A method for configuring a communications receiver comprising the step of updating both a time domain equalizer and a frequency domain equalizer contained in the communications receiver based upon performance data that indicates performance of a communications channel from which the communications receiver receives data.
A computer-readable medium carrying one or more sequences of one or more instructions for configuring a communications receiver, the one or more sequences of one or more instructions including instructions which, when executed by one or more processors, cause the one or more processors to update both a time domain equalizer and a frequency domain equalizer contained in the communications receiver based upon performance data that indicates performance of a communications channel from which the communications receiver receives data.
