Claim Text:
1. A method of improving an ultra wideband digital receiver's sensitivity comprising the steps of: receiving a digital signal stream having multiple identical modulated pulses representing each data bit and having a constant time interval therebetween; applying the received signal stream to a plurality of simultaneous signal processing groups; duplicating the signal stream having multiple identical modulated pulses for each data bit in each signal processing group forming two signal streams of identical modulated pulses each having multiple identical modulated pulses for each data bit in each signal processing group; delaying each said duplicate signal stream in each of said plurality of signal processing groups by a predetermined time to align each first modulated pulse in the same bit of modulated pulses of each of said signal processing group duplicate signal stream with one modulated pulse of the original signal stream, each said first modulated pulse in the same data bit of modulated pulses of each said signal processing group aligning with a different modulated pulse of the original signal stream from that of the other of said plurality of digital processing groups; correlating each of said two signal streams of identical modulated pulses in each signal processing group to produce an output therefrom; magnitude summing the output of each said signal processing groups; summing together each of said magnitude summed signal streams to form a final signal stream; and detecting said summed magnitude signal stream; thereby improving the sensitivity of a receiver.
