Abstract: Disclosed are various embodiments of pairing with a directional code sequence. In one embodiment a method includes discovering that a user device is within proximity of a pairing device. A directional code sequence based upon variations in the position of the user device is obtained and a communication link is established between the user device and the pairing device in response to the directional code sequence. In another embodiment, a system includes a user device and a pairing device configured to establish a communication link with the user device in response to a sequence of position variations of the user device. In another embodiment, a method includes obtaining a sequence of characters corresponding to a directional code sequence from a pairing device and transmitting a signal from a user device to the pairing device from a sequence of positions corresponding to the sequence of characters.

Abstract: A method and system are provided in which a first device may directionally transmitting signals to a second device utilizing beamforming operations on multiple antennas. The first device may receive signals from the second device to establish an anonymous directional peer-to-peer wireless communication link with the second device. The transmitted signals may comprise a request-to-send (RTS) signal and the received signals may comprise a clear-to-send (CTS) signal. In some instances, the direction in which the transmitted signals are sent may be adjusted by changing the weights in the beamforming operation and/or by rotating the plurality of antennas. The transmitted signals may comprise an association identification (ID) corresponding to the first device, which may be embedded in a preamble or other portion of a frame structure. When the link is established, user information, such as profile information, for example, and/or messages may be sent from one device to the other.

Abstract: A signal acquisition system efficiently acquires a transmitted signal even at very low power. The system may synchronize to a preamble structure in the transmitted signal and, for example, determine timing parameters that locate the preamble with respect to system timing or other clock references. The system is particularly effective at acquiring weak power signals and is also robust against significant noise and other impairments, and therefore improves the ability of a receiving device that incorporates the signal acquisition system to acquire the signal and establish communication with other devices.

Abstract: Wireless communication devices are disclosed that are capable of selecting and changing signal polarities depending on channel conditions in order to improve or optimize communication therebetween. When a first polarization direction is deemed inadequate, the devices can switch to communicating via a second polarization. In addition, information relating to received signal qualities in the different polarizations can be stored in each device to allow for quick and efficient exchanges between configurations. Finally, when conditions warrant, the devices can enter a dynamic polarization configuration in which signal polarizations are switched rapidly so as to enjoy benefits of diversity.
