Abstract: A NODE-B/BASE STATION COMPRISES A PLURALITY OF ANTENNA (28,90) FOR RECEIVING USER SIGNALS AND A PATH SEARCHER. THE PATH SEARCHER COMPRISES A SET OF CORRELATORS (34) .EACH CORRELATOR OF THE SET OF CORRELATORS (34) CORRELATES AN INPUTTED USER CODE WITH AN INPUTTED ANTENNA OUTPUT. AN ANTENNA CONTROLLER (30) SELECTIVELY COUPLES AN OUTPUT OF ONE OF THE PLURALITY OF ANTENNAS (34) TO AN INPUT OF EACH.

Abstract: A wireless transmit/receive unit (WTRU) for processing code division multiple access (CDMA) signals. The WTRU includes a modem host and a high speed downlink packet access (HSDPA) co-processor, which communicate over a plurality of customizable interfaces. The modem host operates in accordance with third generation partnership project (3GPP) Release 4 (R4) standards, and the HSDPA co-processor enhances the wireless communication capabilities of the WTRU as a whole such that the WTRU operates in accordance with 3GPP Release 5 (R5) standards.

Abstract: Un método y aparato para proteger y autenticar informacion digital transmitida utilizando numerosas técnicas. El aparato puede ser un sistema de comunicacion inalámbrica multiplex de division de frecuencia ortogonal (OFDM), una estacion base, una unidad de transmision/recepcion inalámbrica (WTRU), un transmisor, un receptor, y/o un circuito integrado (IC). El sistema de comunicacion OFDM inalámbrica incluye un transmisor que incrusta informacion digital en forma esteganográfica en una senal de comunicacion OFDM y transmite en forma inalámbrica la senal de comunicacion OFDM. El sistema incluye, además, un receptor que recibe una senal de comunicacion OFDM y extrae la informacion digital incrustada en forma esteganográfica de la senal de comunicacion OFDM recibida.

Abstract: A Node-B/base station receiver comprises at least one antenna for receiving signals. Each finger of a pool of reconfigurable Rake fingers recovers a multipath component 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 provides each finger of the Rake pool an output of the antenna assigned to that Rake finger. A combiner combines the recovered multipath components for a user to produce data of the user.

Abstract: A Node-B/base station has an access burst detector. The access burst detecto r comprises at least one antenna for receiving signals from users and a pool o f reconfigurable correlators. Each correlator correlates an inputted access burst code at an inputted code phase with an inputted antenna output. An antenna controller selectively couples any output of the at least one antenn a to an input of any of the correlators. A code controller provides to an inpu t of each correlator an access burst code. The code controller controls the inputted code phase of each controller. A sorter/post processor sorts output energy levels of the correlators.

Abstract: A Node-B/base station receiver comprises at least one antenna for receiving signals (2811-28MN). Each finger of a pool of reconfigurable Rake fingers (3 20- 323) recovers a multipath component 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 combines the recovered multipath components for a user to produce data of the user.
