Abstract
A time delay estimation method including the steps of first, estimating a channel response from a received signal, and second, determining a time delay estimate by correlating the estimated channel response with an ideal channel response.Further, a system including a channel estimator and a correlator is provided. The channel estimator is used for estimating a channel response from a received signal and the correlator is used for estimating a time delay using the channel response and an ideal channel response.
