Abstract:
A receiver utilizes a plurality of read elements, each generating a read-back signal in response to a data track positioned beneath the read element. The plurality of read-back signals are each provided to at least one space-time interference cancellation filter, which generates a filtered output that maximizes a signal associated with one of the plurality of data tracks. The filtered output is provided to a one-dimensional Viterbi detector, which is configured to generate in response an output representative of a data sequence written to one of the plurality of data tracks.
