Patent ID: 7245680

Claim:
A method of equalizing a multipath corrupted signal, the method comprising the steps of: (a) receiving a multipath corrupted signal as an input signal, the multipath corrupted signal being modeled as including two rays, including a first ray that is a line-of-sight signal and a second ray that is a second multipath signal; (b) filtering the input signal using a trial equalization filter having a set of one or more filter parameters including a first filter parameter that involves a relative amplitude fraction between the line-of-sight signal and the second multipath signal; (c) determining an optimization criteria from the filtered input signal; (d) repeating steps (b) and (c), varying the set of one or more filter parameters each time steps (b) and (c) are repeated; and (e) selecting the set of one or more filter parameters that results in an optimized optimization criteria value.
