1. Apparatus at a communication station operable at least to receive a data sequence formed of data symbols, said apparatus comprising:
- an estimator adapted to receive indications of values of the data symbols of the data sequence, said estimator formed of multi-dimensional sets of groups of symbols combined over more than one dimension that, once combined, are partitioned into partition sets, said estimator for estimating values of the data symbols of the data sequence.

Abstract
A reduced state sequence estimator, and associated method, for equalizing data symbols communicated during operation of a communication system. The estimator is formed of multi-dimensional states of groups of symbols that are combined over more than one dimension to the multi-dimensional. Once the groups of symbols are formed, the groups are partitioned into partition sets. Equalization operations are performed over multiple time epochs of the trellis formed of the partitioned groups of symbols over multiple time epochs.

12. A method for equalizing a data sequence formed of data symbols to estimate values of the data symbols, said method comprising the operations of:
-
combining symbols of which the data sequence is formable into groups of symbols over more than one dimension;
partitioning the groups of symbols, combined during said operation of combining, into partition sets to form a reduced sequence trellis; and
determining estimated values of the data symbols by applying detected values of the data symbols to the reduced sequence trellis formed pursuant to said operation of partitioning. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
