Patent ID: 7221701

Claim:
A method for wireless communication in a multipath environment, comprising the steps of: a) at a receiver having stored at least one pilot signal associated with a transmitter, receiving signals corresponding to at least one propagation path of a signal transmitted from a transmitter; b) estimating a set of propagation parameters for the at least one propagation path, the step of estimating comprising: (i) generating a windowed version of the received signals; (ii) computing samples of a cross-ambiguity function of one of the stored pilot signals and the received windowed signals; (iii) estimating a set of propagation parameters for the at least one propagation path based on information about one or more peaks of the cross-ambiguity function based on the computed samples; and c) compensating effects of multipath propagation on information-carrying signals from the transmitter using the estimated set of propagation parameters for the at least one propagation path.
