Abstract

See full text

A cluster correlator may be configured with: a first stage comprising a set of first correlators to correlate samples of an input signal with a first predetermined pattern and output an output sample, the set of first correlators to output a sample cluster corresponding to the output sample of the set of first correlators during a switching cycle of the first stage; a filter coupled to an output of the first stage to receive the sample cluster and to produce a processed output sample based on the sample cluster; and a second stage comprising at least one second correlator to receive a processed output sample from the filter and correlate the processed output sample with a second predetermined pattern, and output one or more correlation outputs during a switching cycle of the second stage.
