Abstract
This disclosure is directed to systems and methods for positioning a FFT window using the noise power that is related to ISI By selecting a FFT window position that minimizes the noise power, ISI is reduced or eliminated The techniques can be used in coherent and non-coherent systems Further, noise associated with the Doppler effect is compensated for, allowing the use of these system and methods in time-varying environments, such as mobile applications.
