METHOD AND APPARATUS FOR EFFICIENT DECIMATION BASED CORRELATION TECHNIQUE FOR IDENTIFYING A LOOKED FOR WORD

摘要

A method is described that involves correlating a stream of received samples with a correlation word (522a and 601a in figures 5a and 6a respectively). The stream has one of a plurality of different possible received sampling pattern phases (t1, t2, ...t13 figures 4a and 4b). The correlation word corresponds to a sampling of locked-for symbols where the sampling of locked for symbols has a sampling pattern constructed with different components (522b and 601b in figures 5b and 6b respectively). Each of the components represents one of the different possible received sampling pattern phases (figures 6A through 7C).
