The at least first and second signals encode identical data using a multi-carrier encoding scheme with a predefined cyclic delay between the transmitted signals. The received first and second signals are processed, using the cyclic delay, in order to derive a measure of a phase delay between the first and second signals. Based on the measure of the phase delay, an angle of departure of the first and second signals from the wireless access point to the given location is estimated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Identifying angle of departure of multi-antenna transmitters","description":"A method for signal processing includes receiving at a given location at least first and second signals transmitted respectively from at least first and second antennas of a wireless transmitter.
