  • Method and system for acquiring ultra-wide-bandwidth communications signals using average block searches
    Patent number: 7164720
    Abstract: A method and system acquire a received impulse radio signal by correlating a region, including a plurality of cells, of the received impulse radio signal using multiple time-shifted template signals, each template signal having a different delay to obtain a correlation value for each template signal. The correlation values are averages, and a particular delay associated with a particular template signal having a substantial increase in successive averages to locate a signal cell in the region.
