Abstract: A method for communication includes detecting, at a first station in a wireless network, a beacon transmitted over the wireless network by a second station having multiple antennas. In response to the beacon, a request-to-send (RTS) frame is transmitted over the wireless network using a multi-carrier modulation scheme from the first station to the second station. The first station receives a clear-to-send (CTS) frame transmitted over the wireless network, in response to the RTS frame, by the second station via the multiple antennas using the multi-carrier modulation scheme, and estimates a property of the first station based on the received CTS frame.

Abstract: In at least one embodiment, a system for wireless communication is provided. The system includes a first transceiver and a first mobile device. The first mobile device includes the first transceiver and is programmed to receive a first wireless signal and a second wireless signal and to process the first wireless signal and the second wireless signal based on a first internal clock associated with the first mobile device. The first mobile device is further programmed to determine a time of arrival (TOA) of the first wireless signal to provide a first TOA signal and to determine the TOA of the second wireless signal to provide a second TOA signal. The first mobile device is further programmed to obtain a difference between the first TOA signal and the second TOA signal to provide a first difference TOA signal that is independent of the first internal clock.

Abstract: A method for communication includes simultaneously transmitting over a wireless network from a first station to a second station at least first and second request-to-send (RTS) frames in different, respective first and second frequency channels. The first station receives first and second clear-to-send (CTS) frames transmitted in the first and second frequency channels, respectively, by the second station over the wireless network in response to the first and second RTS frames. At least one property associated with the first station is estimated by processing information extracted from both the first and second received CTS frames.

Abstract: A method for signal processing includes receiving via first and second antennas (34) respective first and second input signals in response to an output signal that is transmitted from a wireless transmitter (27, 28, 30) and encodes a predefined sequence of symbols. A temporal correlation function is computed over the first and second input signals with respect to one or more of the symbols in the predefined sequence so as to identify respective first and second correlation peaks and extract respective first and second carrier phases of the first and second input signals at the first and second correlation peaks. A phase difference between the first and second signals is measured based on a difference between the first and second carrier phases extracted at the first and second correlation peaks. Based on the measured phase difference, an angle of arrival of the output signal from the wireless transmitter is estimated. There is additionally provided, in accordance with an embodiment of the invention, a method for location finding, which includes receiving radio signals transmitted between a plurality of fixed transceivers having multiple antennas at different, respective first locations and a mobile transceiver at a second location. A respective phase difference is detected between the received radio signals that are associated with each of the multiple antennas of each of the fixed transceivers. Multiple loci are computed, corresponding respectively to respective angles between each of the fixed transceivers and the mobile transceiver based on the respective phase differences. Location coordinates of the mobile transceiver are found based on the angles and the transmit locations of the transmitters by identifying an intersection of the loci as the second location of the mobile transceiver.

Abstract: 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 (34) of a wireless transmitter (24). 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 (θ) of the first and second signals from the wireless transmitter to the given location is estimated.

Abstract: In at least one embodiment, an apparatus for wireless communication is provided. The apparatus includes a transceiver, a dedicated modem, a frequency converter, at least one controller and a bus. The transceiver receives a first wireless signal associated with a first predefined wireless communication standard and a second wireless signal associated with a second predefined wireless communication standard. The dedicated modem is capable of processing the first wireless signal. The frequency converter down converts a second frequency of the second wireless signal. The controller receives data on the second wireless signal and processes the data on the second wireless signal. The bus is configured to divert the data from the second wireless signal from being received at the dedicated modem by directly transmitting the data from the second wireless signal to memory. The controller is further programmed to access the memory for processing the data on the second wireless signal.
