Abstract: Un Nodo B/estación base tiene un detector de ráfaga de acceso. El detector de ráfaga de acceso comprende al menos una antena para recibir senales de usuarios y un grupo de correlacionadores reconfigurables. Cada correlacionador correlaciona un código de ráfaga de acceso ingresado en una fase de código ingresada con una salida de antena ingresada. Un controlador de antena acopla selectivamente cualquier salida de la al menos una antena a una entrada de cualquiera de los correlacionadores. Un controlador de código la provee a una entrada de cada correlacionador, un código de ráfaga de acceso. El controlador de código controla la fase de código ingresada de cada controlador. Un clasificador/post-procesador clasifica niveles de energía de salida de los correlacionadores.

Abstract: The system uses a modified subscriber station to act as a simulated or emulated base station. This emulated base station essentially differs from the subscriber station only in being able to initiate the synchronization process, whereas the subscriber unit only acts to scan the RF signals sent out by the emulated base station until it finds the frequency and slot assigned to it. - The signal received from one station is separated into high band and low band energy frequencies. The high band energy output is substracted from the low band energy output to obtain a resultant signal, which is stripped of its sign determine only the amplitude. The stripped signal is accentuated while substantially filtering out noise, and fed to a voltage controlled crystal oscillator (VCXO) which provides the timing at the other station.

Abstract: Un método para ajustar los parámetros operativos de un dispositivo inalámbrico para su uso en una red de comunicación inalámbrica se inicia ingresando y almacenando configuraciones de situación. Cuando una comunicación es recibida en la red para el dispositivo inalámbrico, se determinan la presencia del dispositivo inalámbrico. Las configuraciones de situación son aplicadas en base a la presencia del dispositivo inalámbrico. Se informa al dispositivo inalámbrico de la comunicación a través de configuraciones de situación aplicadas.

Abstract: A Node-B/base station comprises a plurality of antennas (28I - 28M) for receiving user signals and a path searcher. The path searcher comprises a se t of correlators (42-1, 42-2 ~ 42-P). Each correlator of the set of correlator s correlates an inputted user code with an inputted antenna output. An antenna controller selectively couples an output of one of the plurality of antennas to an input of each.

Abstract: A NODE-B/BASE STATION RECEIVER COMPRISES AT LEAST ONE ANTENNA (28) FOR RECEIVING SIGNALS. EACH FINGER OF A POOL OF RECONFIGURABLE RAKE FINGERS (32) RECOVERS A MULTIPATH COMPONENT (16) OF A USER AND IS ASSIGNED A CODE OF THE USER, A CODE PHASE OF THE MULTIPATH COMPONENT AND AN ANTENNA OF THE AT LEAST ONE ANTENNA. AN ANTENNA/RAKE FINGER POOL INTERFACE (30) PROVIDES EACH FINGER OF THE RAKE POOL AN OUTPUT OF THE ANTENNA ASSIGNED TO THAT RAKE FINGER. A COMBINER (42) COMBINES THE RECOVERED MULTIPATH COMPONENTS FOR A USER TO PRODUCE DATA OF THE USER.
