Patent ID: 7050517

Claim:
A receiver system comprising: a group of one-dimensional (“1-D”) receivers each comprising (a) an input section that processes a corresponding different one of a group of receiver input signals respectively corresponding to the receivers according to a process that comprises serially filtering and digitizing that input signal to generate a corresponding processed signal as a stream of filtered digitized values and (b) an equalizer that performs equalization on an intermediate signal comprising the filtered digitized values or further values generated from the filtered digitized values to produce a corresponding equalized signal as a stream of equalized values; a group of 1-D symbol selectors respectively corresponding to the receivers, each symbol selector providing a corresponding symbol signal as a stream of 1-D symbols chosen, from a set of predefined 1-D symbols, to be respectively substantially closest to the equalized values of the equalized signal of the corresponding receiver, data for a feedback signal used by the equalizer in each receiver for generating the current equalized value of that receiver's equalized signal being supplied from a lookup table as a function of at least one previous symbol provided from the corresponding symbol selector; and a multi-dimensional decoder that furnishes a stream of multi-dimensional symbols in response to the streams of 1-D symbols.
