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 comprises a plurality of antennas (28I - 28M) for receiving user signals and a path searcher. The path searcher comprises a set of correlators (42-1, 42-2 … 42-P). Each correlator of the set of correlators 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:
In an integrated reception apparatus, information received from a plurality of sources is supplied to an A/D (7) and a DSP (8); a controller (8a) of the DSP (8) determines an order of priority of the information, and processes the information based on the order of priority. The order of priority is determined based on an error correction ability, allowable error ratio, or degree of importance of the information and, by performing demodulation of the signals lower in priority with interruption or curtailment processing, the capacity of the DSP (8) is efficiently used.
Abstract:
A downlink communication path is established from a transmitter (200) of the central terminal (10) to a receiver (202) of the subscriber terminal (20). A downlink signal (212) is transmitted from the transmitter (200) to the receiver (202) during setup and operation of the wireless telecommunications system (1). The downlink signal (212) includes an overhead channel (224) having a code synchronization signal (234). The code synchronization signal (234) is capable of adjusting a phase of a transmitter (204) in the subscriber terminal (20). A receiver (206) in the central terminal (10) monitors an uplink signal (214) transmitted by the transmitter (204) in the subscriber terminal and provides changes to the code synchronization signal (234) such that the transmitter (204) is synchronized to the receiver (206). Synchronization of the transmitter (204) in the subscriber terminal (20) to the receiver (206) in the central terminal (10) facilitates establishment of an uplink communication path from the subscriber terminal (20) to the central terminal (10).
Abstract:
A system and method for multi-radio control unifies disparate radio technologies and communication protocols and abstracts them such that a user of a personal electronic device having a plurality of disparate radios is not required to know or understand the radio technology needed to connect to a remote wireless device or service. An intermediate layer receives requests from a user interface application, generates specific driver commands to each radio, and returns information received from each radio to the user interface application module. A user interface application module initiates a search for available remote wireless devices, provides the user with information regarding the available remote wireless devices, and establishes a connection to an available remote wireless device in response to a user selection. The user interface application module also presents notifications to the user, and also handles disconnect requests and security credential dialogs.
Abstract:
PROBLEM TO BE SOLVED: To provide a Node-B capable of handling varying conditions in a flexible manner while efficiently utilizing hardware. SOLUTION: A Node-B has an access burst detector. The access burst detector comprises at least one antenna (28 1 -28 m ) for receiving signals from users and a pool of reconfigurable correlators (36 1 -36 o ). Each correlator correlates an input access burst code at an input code phase with an input antenna output. An antenna controller (30) selectively couples an arbitrary output of the at least one antenna to an input of an arbitrary correlator. A code controller (40) provides an input of each correlator with an access burst code. The code controller (40) controls the input code phase of each controller. A sorter (38) sorts output energy levels of the correlators. COPYRIGHT: (C)2008,JPO&INPIT
