Abstract:
1. A method for controlling in an ultra wide bandwidth (UWB) receiver transitions between synchronization states that include an acquisition mode and a tracking mode, comprising the steps of: identifying an in-band measure of a signal to noise ratio of an incoming UWB signal; comparing the in-band measure of signal to noise ratio identified in the identifying step with an in-band signal to noise ratio threshold; transitioning between the acquisition mode and the tracking mode when in the comparing step it is determined that the in-band measure of signal to noise ratio has satisfied a predetermined criteria relative to in-band signal to noise ratio threshold; and setting a number of samples of the incoming UWB signal to a predetermined number so as to controllably establish a predetermined performance level with regard to when to control a transition between the acquisition mode and the tracking mode.
