    摘要: A circuit to detect position signals in a mobile station includes a general-purpose processor to generate instructions for execution of at least one signal detection algorithm and to carry out at least one other function not associated with the signal detection algorithm, special-purpose hardware blocks responsive to the instructions of the general-purpose processor to execute the at least one signal detection algorithm, and at least one of the general-purpose processor and the special-purpose hardware blocks configured to execute at least one efficiency process to optimize performance of the at least one signal detection algorithm. Methods and machine-readable medium implementing the method steps are also disclosed.

    摘要: Methods and apparatus are provided for use in devices adapted to receive signals from at least one satellite positioning system (SPS). As part of at least one search for a transmission from a space vehicle (SV) associated with the SPS, the methods and apparatuses may correlate a code associated with the SV with a received signal to establish a plurality of correlation values, sample at least a portion of the correlation values during the search, and selectively transitioning the search early or prematurely based, at least in part, on at least one of the sampled correlation values.

    摘要: In a radio frequency (RF) receiver, a receiver RF chain is tuned to a first (e.g., global positioning system (GPS)) channel to permit receipt of a first (e.g., GPS) signal over the first (e.g., GPS) channel on the receiver RF chain during a first time duration. The receiver RF chain is tuned to a second (e.g., cellular page) channel to permit receipt of a second (e.g., cellular page) signal over the second (e.g., cellular page) channel on the receiver RF chain during a second time duration, following the first time duration. The first (e.g., GPS) signal is processed during the first time duration and the second time duration, without any apparent interruption of the first (e.g., GPS) signal during the second time duration. The processing, for example, treats the actual interruption as a temporary, short term fade of the first (e.g., GPS) signal during the second time duration, or provides a bridge signal (e.g., an estimated GPS signal on the receiver RF chain or an actual GPS signal received on another receiver RF chain) during the second time duration.

    摘要: Apparatus and methods of implementing code space search of received signals are described herein. A code space search is implemented as a searcher (220) that perform a subtask that is dynamically reconf igurable at each boundary of an initial integration time. Each particular subtask sets forth a programmabl configuration of coherent integration hypothesis that are performed during th initial integration time. The searcher stores the results of the coherent integration hypothesis in a first portion of memory. A search accelerator (250) operates on the initial integration results. The search accelerator can perform coherent integration of various frequency bins of different timing hypothesis, can generate energy values of the coherent integration results, and can generate a non-coherent energy summation. The energy values of the coherent integrations and non-coherent energy summations are stored in a second portion of memory. The ability to reconfigure the subtasks and accelerator operation provides flexibility in search space dimensions.
