Abstract
A method of estimating a channel response of a channel is provided that includes transforming a frequency domain signal received via the channel into a time domain signal and searching the time domain signal for a location of minimum energy. The method also includes padding the time domain signal with zeroes at the location of minimum energy and transforming the padded time domain signal to a second frequency domain signal. The second frequency domain signal is used as an estimated channel response for the channel.
