Ultra-wideband correlating receiver
First Claim
1. An ultra-wideband receiver comprising:
- a template generator structured to generate a local signal similar to an incoming signal;
a single correlator structured to correlate the incoming signal with the local signal;
at least one filter in communication with the correlator;
an energy estimator in communication with the at least one filter; and
a pulse detector in communication with the at least one filter.

Abstract
A receiver for ultra-wideband communications is provided. One feature of the receiver architecture is that includes only a single correlator. The receiver may be used in wireless and wire communication mediums. The single correlator may be used to update a locally generated signal based on an incoming signal and detect data. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules that allow a reader to quickly ascertain the subject matter of the disclosure contained herein. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

24. A method of receiving and demodulating an ultra-wideband signal, the method comprising the steps of:
-
receiving the ultra-wideband signal, the ultra-wideband signal comprising a plurality of ultra-wideband pulses;
generating a template signal;
correlating the ultra-wideband signal with the template signal;
estimating a coarse timing reference from a correlation of the ultra-wideband signal and the template signal;
updating the template signal based on the coarse timing reference;
correlating the ultra-wideband signal with the updated template signal; and
detecting an ultra-wideband pulse from the correlation of the ultra-wideband signal and the updated template signal. - View Dependent Claims (25, 26, 27)
