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.
Claims5
A method for acquiring a received impulse radio signal, comprising:
- correlating a region, including a plurality of cells, of the received impulse radio signal using a plurality of template signals, each template signal having a different delay to obtain a correlation value for each template;
- averaging the correlation values;
- determining a difference between successive averages of the correlation values;
- and
- selecting a particular delay associated with a particular template signal having a substantial increase in the difference of the successive averages to locate a signal cell in the region.
A system for acquiring a received impulse radio signal, comprising:
- means for correlating a region, including a plurality of cells, of the received impulse radio signal using a plurality of template signals, each template signal having a different delay to obtain a correlation value for each template signal;
- means for averaging the correlation values;
- and
- means for selecting a particular delay associated with a particular template signal having a substantial increase in successive averages to locate a signal cell in the region.
