The present invention is for a method and apparatus to improve an Ultra Wideband (UWB) digital receiver's performance sensitivity. A transmitted signal stream has each data bit having multiple identical modulated pulses separated by a constant time interval. The received signal stream is duplicated (26, 27, 30) to create a second signal stream of identical modulated pulses to the original signal stream. The duplicated signal stream is delayed by the constant time interval between identical modulated pulses and the two signal streams correlated (26, 32) to form one signal stream which is detected (34) to improve the sensitivity of the receiver (Figure 1).
