1. A method for generating ultra-wide band communication signals comprising the steps of:
- (a) generating a baseband signal in the frequency domain;
(b) processing the baseband signal to generate an ultra-wide baseband signal having a desired bandwidth in which frequency is a function of time; and
(c) notching the ultra-wide baseband signal in the time domain to generate an ultra-wide band communication signal having desired signal frequencies precisely excised from the expanded baseband signal.

Abstract
A system and method for generating an ultra-wide band communication signal having data occurring a specific frequencies precisely excised at baseband. The data to be transmitted is transformed into a function of time where the data to be excised can be removed in the time domain. After the data has been successfully removed in the time domain, the data is then transmitted in the frequency domain in which no data is transmitted at the frequencies where the data was precisely excised.
