Abstract: Systems, apparatus and methods for determining a cyclic shift delay (CSD) mode from a plurality of CSD modes is disclosed. A received OFDM signal is converted to a channel impulse response (CIR) signal in the time domain and/or a channel frequency response (CFR) signal in the frequency domain. Matched filters and a comparator are used to determine a most likely current CSD mode. Alternatively, a classifier is used with a number of inputs including outputs from two or more matched filters and one or more outputs from a feature extractor. The feature extractor extracts features in the time domain from the CIR signal and/or in the frequency domain from the CFR signal useful in distinguishing various CSD modes.

Abstract: Various techniques are provided which may be implemented as methods, apparatuses and articles of manufacture for use by a mobile device. In certain example implementations, a mobile device may process a barometric pressure measurement indicative of an altitude effect and a weather effect to determine a first parameter corresponding to the altitude effect and a second parameter corresponding to the weather. Such a mobile device may further determine whether it may be transitioning or may have transitioned from an initial level to another level of a multiple level structure based, at least in part, on the first and second parameters.

Abstract: Disclosed are systems, apparatus, devices, methods, media, products, and other implementations, including a method that includes determining, at a first wireless device comprising multiple transmit antennas, at least one signal transmission characteristic according to at least one pre-determined varying transmission characteristic determination process. The at least one transmission characteristic includes, for example, a transmit antenna selected from the multiple transmit antennas, a beam characteristic, a cyclic delay diversity parameter, and/or any combination thereof. The method also includes transmitting from the first wireless device to a second wireless device a signal using the at least one signal transmission characteristic determined according to the at least one pre-determined varying transmission characteristic determination process. The transmitted signal is configured to facilitate position determination of the second wireless device upon deriving at the second wireless device a reconstructed value of the at least one signal transmission characteristic determined at the first wireless device.

Abstract: The disclosure generally relates to position sensors, and more particularly to repair of carrier-phase cycle slips using displacement data. An apparatus for use in position sensing may include a displacement sensor, a positioning signal receiver, a memory, and a processor coupled to the displacement sensor, the positioning signal receiver, and the memory. The processor and memory may be configured to processor and memory are configured to detect a loss of lock of a first carrier tracking loop associated with the first set of carrier-phase measurements, wherein the first carrier tracking loop is associated with a first integer ambiguity, estimate, based on the displacement data, an ambiguity increment to the first integer ambiguity subsequent to the detected loss of lock, and resolve a second integer ambiguity associated with the second set of positioning signals based on the first integer ambiguity and the estimated ambiguity increment.
