Systems and methods for processing data with linear phase noise predictive filter

摘要

Systems, methods, devices, circuits for data processing, and more particularly to systems and methods for data processing with a linear phase noise predictive filter. A data processing system includes an equalizer circuit operable to filter a digital data input to yield equalized data, a linear phase noise predictive finite impulse response filter operable to filter the equalized data to yield filtered data, and a data detector circuit operable to apply a data detection algorithm to the filtered data to yield a detected output. The greatest tap coefficient for the linear phase noise predictive finite impulse response filter is at a center tap.
