Beschreibung
Zusammenfassung:	A method for operating a wireless receiver includes receiving wireless signals from a transmitter at a first antenna and a second antenna. The wireless signals include a signal carrier and one or more data symbols modulated onto the signal carrier. The one or more data symbols in the wireless signal are decoded to determine a symbol phase contribution. The phase of the wireless signals at the first antenna and the second antenna during one or more symbol periods is estimated to provide a first set of phase measurements and a second set of phase measurements, respectively. The symbol phase contribution is removed from the first set of phase measurements and the second set of phase measurements to provide a first corrected set of phase measurements and a second corrected set of phase measurements, respectively, which are used to estimate an angle of arrival of the wireless signals.
