Abstract: A novel and improved method and apparatus for searching is described. This searcher combines the ability to search multiple offsets of single pilots, such as those found in the IS-95 system, with the ability to search multiple pilots, such as those found in a GPS location determination system. Both typ es of searching can be done in a single architecture combining the parallel computation features of a matched filter with the flexibility of allowing a variable number of non-coherant accumulations to be performed at high speed for a wide range of search hypotheses in a resource efficient manner. This invention allows for parallel use of the matched filter structure in a time- sliced manner to search multiple windows. In addition, the searcher allows f or optional independent Walsh decovering for each search window. The time-shari ng approach allows for optional frequency searching of any offset.

Abstract: Un buscador programable de filtro adaptado que comprende: un registro de desplazamiento (401A-K, 403A-K, 800A-K) que funciona como un registro de desplazamiento único cuando recibe un primer tipo de datos y que funciona como registros de desplazamiento múltiples cuando recibe un segundo tipo de datos, siendo el primer tipo de datos recibido a partir de una fuente única y siendo recibido el segundo tipo de datos a partir de una pluralidad de fuentes; una pluralidad de generadores PN para generar una pluralidad de secuencias PN; un filtro adaptado cargable para cargar dicha pluralidad de secuencias PN, des-escalonar dichos conjuntos de datos entrantes y sumar los resultados intermedios; y un acumulador (810, 816) para recibir dichas sumas y acumularlas en conjuntos para producir un conjunto de sumas acumuladas.

Abstract: [0072] A SPREAD SPECTRUM WIRELESS DEVICE (100) MAY INCLUDE A RECEIVER (110), A SEARCHER (128), A SEARCH CONTROLLER (130) AND OTHER FEATURES. THE SEARCH CONTROLLER (130) SELECTIVELY GENERATES CONTROL SIGNALS TO CONTROL THE SEARCHER (128) , WHICH SEARCHES FOR A SPREAD-SPECTRUM SIGNAL. IN ONE EMBODIMENT, THE ARCHITECTURE OF THE SEARCHER (128) IS DYNAMICALLY CONFIGURABLE BY THE SEARCH CONTROLLER (130) TO SELECTIVELY SEARCH MULTIPLE CHANNELS USING MULTIPLE FREQUENCY BINS FOR THE SIGNAL.(FIG 1)

Abstract: A spread spectrum wireless device (100) may include a receiver (110), a searcher (128), a search controller (130) and other features. The search controller (130) selectively generates control signals to control the searcher (128), which searches for a spread-spectrum signal. In one embodiment, the architecture of the searcher (128) is dynamically configurable by the search controller (130) to selectively search multiple channels using multiple frequency bins for the signal.

Abstract: The present invention is a novel and improved method and apparatus for performing position location in wireless communications system. One embodiment comprises a method for performing position location using a set of signals transmitted from a set of satellites including the steps of storing coarse search data, performing a coarse search on said coarse search data for each satellite from said set of satellites, receiving fine search data, performing a set of fine searches on said fine search data, each fine search being performed on a different time segment of said fine search data, and reporting results.
