Abstract
A receiver receives packets without prior knowledge of their bandwidths. The receiver calculates a first auto-correlation function for a first channel, a second auto-correlation function for a second channel, and a dot product of the first auto-correlation function and the second auto-correlation function. A packet is detected and its bandwidth classified based at least in part on the dot product.
