Abstract
A system and method is provided for improving the operating range for UWB communication systems by increasing the margin between true correlation peaks and false correlation peaks in a received UWB signal. A received signal is first correlated with a UWB kernel before being correlated with the PRN code. The UWB kernel is a very short UWB pulse having the same pulse shape as the UWB signal pulses. By pre-correlating the received signal with the UWB kernel at least once prior to correlating with the PRN code, the margin between true correlation peaks and false correlation peaks is substantially improved.
