Method and system for controlling an adaptive, blind, fractionally spaced equalizer

摘要

The present invention includes a method and system for controlling an equalizer equalizing data transmitted a communications channel which is oversampled at an oversampling rate of M. The method of the present invention includes the steps of initializing a plurality of data pointers and a first buffer stored in an input memory (22); generating a buffer full flag in response to filling the first buffer with a pre-determined number of data samples; initializing a counter (28) in response to the buffer full flag, the counter (28) generating an enable signal every M cycles; equalizing a portion of the pre-determined number of data samples in response to the enabling signal using an equalizer (20), where the portion of the pre-determined number of data samples is located using the plurality of data pointers; and adjusting the plurality of data pointers in response to the equalizing step using an FSE controller (24).
