Patent ID: 7305052

Claim:
An ultra-wideband (UWB) communication receiver, comprising: a feedback amplifier having an input line and an output line, said input line electrically coupled to a common input line, wherein said feedback amplifier, said input line and said output line are configured as a feedback loop so as to loop at least once one or more transmitted pulse pairs received on said common input line, wherein said transmitted pulse pairs have a predetermined encoded data and a predetermined symbol repetition rate; a primary delay electrically coupled to said common input line and configured to reproduce a predetermined primary lag interval D n of said one or more transmitted pulse pairs; one or more secondary delays electrically coupled to said common input line and configured to produce one or more non-zero lag intervals d nk of said received pulse pairs, a plurality of pulse multipliers and finite integrators designed to generate a plurality of data values indicative of a second order statistical function of said received pulse pairs resulting from said primary delay and from said one or more secondary delays, a bank of filters to match a plurality of stored sampled values indicative of a second order statistical function of said one or more transmitted pulse pairs with said generated values indicative of a second order statistical function resulting from said primary and said one or more secondary delays of said received pulse pairs; and a hard decision block designed to produce one or more output bits based on matching said sampled values indicative of said second order statistical function and said generated values indicative of said second order statistical function of said received pulse pairs that indicates encoded information of said transmitted pulse pairs.
