Abstract:
1. An apparatus comprising: a feed forward filter to receive incoming signals; a first combiner coupled to receive an output of the feed forward filter; a correlator unit to generate a set of correlator outputs, the correlator unit having a plurality of correlators each coupled to receive an input signal from an output of the first combiner and one of a plurality of reference signals, each of the reference signals pre-compensated with expected intra-codeword interference of an associated codeword of a codeword set, wherein the correlator unit comprises a bank of filters, each bank comprising a filter coupled to receive the associated codeword, a second combiner coupled to receive the associated codeword and an output of the filter, and one of the plurality of correlators coupled to receive outputs of the first combiner and the second combiner; and a codeword selector coupled to the set of correlator outputs to determine a received codeword therefrom.
