摘要： 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 (406). 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 (408).

摘要： A method for communication includes detecting, at a first station (28) in a wireless network, a beacon transmitted over the wireless network by a second station (24) having multiple antennas (34). 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 an angle of transmission from the second station to the first station based on the received CTS frame.

摘要： 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.

摘要： An apparatus for generating a mosaic for a wireless communication system. The apparatus includes memory and a server. The server is programmed to receive first information from an associated access point that is indicative of a first receiver time stamp and a second receiver time stamp. The server is further programmed to determine a first difference between the first receiver time stamp and the second receiver time stamp to generate a first difference value and to receive second information that is indicative of a third receiver time stamp and a fourth receiver time stamp. The server is further programmed to determine a second difference and to generate a second difference value. The server is further programmed to determine that packets as transmitted by the mobile device are the same based on the first difference value and the second difference value being within a predetermined receiver time error range.

摘要： 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.

摘要： A method for communication includes identifying a media access control (MAC) address of a mobile station (28) of interest. Independently of receiving any probe request frame from the mobile station, a probe response frame addressed to the identified MAC address is transmitted over a wireless local area network (WLAN). An acknowledgment of the probe response frame is received from the mobile station and is used in ascertaining a location of the mobile station.

摘要： In at least one embodiment, a system for providing locationing multipath mitigation for wireless communication is provided. The system includes a receiver having at least one controller. The at least one controller is programmed to; receive a first narrowband wireless signal including a predetermined symbol from a transmitter across a wideband transmission channel that exhibits a multipath condition and additive noise, the first narrowband wireless signal being convoluted with the wideband channel to form a first received signal and to perform autocorrelation on the first received signal to extract the predetermined symbol. The at least one controller is further configured to filter the extracted predetermined symbol to deconvolve the first received signal to minimize the effects of the multipath condition and the additive noise to provide a first deconvoluted signal.
