Abstract: A method according to an embodiment obtains a list of peaks for each of a number of frequency hypotheses. Each peak has an energy result and corresponds to a code phase hypothesis. Embodiments include methods and apparatus that may be used in identifying a location of a signal (such as a GPS signal) in a two-dimensional search space. Location information may be further applied to operations such as signal acquisition, signal tracking, position location of a receiver, and timing operations such as the synchronization of one or more other processes.

Abstract: A turbo code interleaver (100) using linear congruential sequences may be employed as a two-dimensional interleaver (16) in a turbo coder (10) that also includes first and second constituent encoders (12, 14). The interleaver (16) and the first encoder (12) are each configured to receive input bits. The first encoder (12) produces output symbols (22, 24) therefrom. The interleaver (16) receives the input bits (20) sequentially by row. A linear congruential sequence recursion algorithm within the interleaver (16) serves to pseudo-randomly rearrange, or shuffle, the bits within each row of the interleaver (16). The bits (26) are then output from the interleaver sequentially by column. The second encoder (14) is configured to receive the interleaved bits from the interleaver. The second encoder (14) produces output symbols (28) therefrom. The two streams of output symbols (22, 24) are multiplexed together, with appropriate puncturing. If desired, the linear congruential recursion sequence can be generated in reverse. Also if desired, a bit reversal technique can be used in the interleaver (16) to rearrange, or shuffle, the rows of the interleaver (16).

Abstract: A receiver according to one embodiment includes a frequency control unit configured to receive a stream of samples including a plurality of received instances of a transmitted signal. The frequency control unit is configured to output a first correction signal (e.g. indicating a rotation) that is based on more than one of the received instances and a second correction signal (e.g. to control an oscillator) that is also based on more than one of the received instances. In some embodiments, a controlled oscillator is used to receive and/or transmit another signal, such as a signal received from a GPS space vehicle. In other embodiments, the received instances are from a GPS signal. In further embodiments, a fixed-frequency oscillator is used, and the second correction signal is used to receive and/or transmit another signal, such as a GPS signal.

Abstract: A method of and system for detecting an interfering multi-path condition is provided. A parameter is determined from a pulse of a correlation function derived from a received signal. The parameter is examined to determine if it is inconsistent with a non-interfering multi-path hypothesis. If so, an interfering multi-path condition is detected.

Abstract: A method of and system for estimating a parameter of a local maxima or minima of a correlation function derived from a received signal . An interpolated local maxima or minima is determined. An interpolation offset is then derived, comprising a deviation between locations of the interpolated and sampled local maxima or minima of the function. An estimate of the parameter is derived from the interpolation offset.

Abstract: According to one embodiment, a demodulation system, such as DPSK in a SPS system can be used with soft decision information to correct bit errors.

Abstract: A system, method and apparatus for providing location services whereby location determination and location disclosure are treated as separate and independent processes. Location determination may be performed (as necessary) via a first set of network entities to obtain location information for a mobile station. The location information may be cached for subsequent disclosure to any number of applications. Location disclosure may be performed (when requested) via a second set of network entities to provide the location information. Location determination may utilize a first security procedure for authorization and to obtain a first session key used for location determination. Location disclosure may utilize a second security procedure for authorization and to obtain a second session key used for location disclosure. For a roaming mobile station, location determination may be performed via a serving network and location disclosure may be performed via a home network.

Abstract: An application executed within a mobile station to be triggered only by a network element, such as a mobile positioning center (MPC) or a Mobile Center (MC). The network element is coupled to a base station. The network element is responsible for authorizing an application that is either resident within the mobile station or that is run in a device that is resident elsewhere in the network. The mobile station communicates with the network element over a communication link through the base station and other infrastructure components. The mobile station will only respond to attempts to trigger particular operations (e.g., run particular applications) if the mobile station receives a short message services (SMS) message as defined by Interim Specification 637A (IS-637A) which is published by the Telecommunication Industry Association (TIA)/Electronics Industry Association (EIA). More specifically, that SMS message must include an SMS Teleservice Identifier that has a particular pre-assigned value.
