RECEIVER WITH SIGNAL ARRIVAL DETECTION CAPABILITY

摘要

A receiver includes a phase click detector, a controller, and a comparator. The phase click detector detects phase clicks in an input signal, where a phase click corresponds to a change in phase of at least a first threshold. The controller is coupled to the phase click detector for calculating a number of phase clicks within one or more time periods. The comparator compares the number of phase clicks within the one or more time periods, and provides an arrival signal if the number of phase clicks is less than a second threshold.
