ABSTRACT:
A circuit for processing binary sequences is designed with a plurality of stages (530–534) coupled to provide plural signal paths (526,528). Each stage includes respective signal paths (550,562) for a first Ra1(k) and a second Rb1(k) data sequence. Each stage further includes a respective delay circuit (502) having a different delay from said respective delay circuit of each other stage (504,506) of the plurality of stages. A stage having a greatest delay (502) precedes other stages (504,506) in the plurality of stages of at least one of the plural signal paths.
