Abstract:
A data processing system includes an equalizer circuit operable to equalize digital data according to tap coefficients to yield equalized data, a tap coefficient adaptation circuit operable to adapt the tap coefficients based at least in part on a scaled error signal, a data detector operable to apply a data detection algorithm to the digital data to generate hard decisions and soft decisions, an error calculation circuit operable to calculate an error signal based on the equalized data and on the hard decisions, and a scaling circuit operable to scale the error signal based on the soft decisions to yield the scaled error signal.

Systems and method relating generally to data processing, and more particularly to systems and methods for fragmenting a data set and recovering the fragmented data set.
Abstract:
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.

Abstract:
A storage system includes a storage medium operable to maintain a data set, a read/write head assembly operable to write the data set to the storage medium and to read the data set from the storage medium, a multi-level encoder operable to encode the data set at a plurality of different code rates before it is written to the storage medium, and a multi-level decoder operable to decode the data set retrieved from the storage medium and to apply decoded values encoded at a lower code rate when decoding values encoded at a higher code rate.
