Abstract
A correlator has a feedback circuit having a first input coupled to an incoming data stream, a second input and an output. A data register is to store an incoming data stream having a number of candidate bits, the data register having an output coupled to the second input of the feedback circuit. A code register is to store a known code having a predetermined number of code bits and a comparator is to compare a portion of the incoming data stream to a portion of the known code.
