  • Patent number: 11290545
    Abstract: Described herein are method and apparatus for servicing software components of nodes of a cluster storage system. During data-access sessions with clients, client IDs and file handles for accessing files are produced and stored to clients and stored (as session data) to each node. A serviced node is taken offline, whereby network connections to clients are disconnected. Each disconnected client is configured to retain its client ID and file handles and attempt reconnections. Session data of the serviced node is made available to a partner node (by transferring session data to the partner node). After clients have reconnected to the partner node, the clients may use the retained client IDs and file handles to continue a data-access session with the partner node since the partner node has access to the session data of the serviced node and thus will recognize and accept the retained client ID and file handles.

  • Publication number: 20150304153
    Abstract: A wireless communications device using a multi-carrier modulation communication signal may include a transmitter and a controller operable with the transmitter. The controller may be configured to reduce a peak-to-average power ratio (PAPR) associated with the multi-carrier modulation communication signal by at least generating a plurality of intermediate multi-carrier modulation communication signals based upon respective different permutations of a Walsh transformation matrix, and selecting a given intermediate multi-carrier modulation communication signal for transmission as the multi-carrier modulation communication signal based upon a PAPR associated therewith.

  • Publication number: 20080075150
    Abstract: A single, common correlation filter (CF) core is provided in a receiver for recovery of data from received code division multiple access (CDMA) signals. Signals are received over CDMA channels with different data rates, where the received signals include user information such as pilot and data symbols that have been spread according to different despreading rates including tier 1, tier 2 and tier 3 rates, where tier 1 is the smallest despreading rate. The received signal is correlated at the smallest despreading rate in the correlation filter (CF) by time multiplexing delayed versions of the pseudorandom noise (PN) code. The correlated information is then demultiplexed and pilot-aided QPSK demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve tier 2 and tier 3 despreading rates. According to an embodiment, the three strongest multipaths components in terms of the received power are selected in a window or time period for optimal information recovery.

  • Publication number: 20080019277
    Abstract: A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions.

  • Publication number: 20070189325
    Abstract: A Station Management Entity (SME) steers a directional antenna for a station to communicate with an Access Point (AP) in an 802.11 protocol system. The SME can steer the antenna before or after an 802.11 station has authenticated and associated with the Access Point. During a passive scan, the steering process cycles through the available antenna positions and monitors an AP beacon signal to determine a best position based on, for example, a Received Signal Strength Indication (RSSI). During an active scan where access probing is used, the steering process cycles through the antenna positions and monitors a probe response to determine the best antenna position. Additional scans may be performed based on a decision that the received signal level of the currently selected antenna position has dropped below a predetermined threshold.

  • Publication number: 20070121939
    Abstract: In a communication system comprising a plurality of transmit/receive units (TRUs), a method for embedding a watermark into data includes modifying a carrier signal containing data to embed watermark information. The modified carrier signal is transmitted. A receiver receives the modified carrier signal and extracts the watermark information from the modified carrier signal.

  • Publication number: 20070076816
    Abstract: The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment.

  • Publication number: 20070047475
    Abstract: A digital satellite radio system includes a content server for providing digital satellite radio channels, a satellite for broadcasting the digital satellite radio channels, and a terrestrial repeater for broadcasting the digital satellite radio channels. A micro-repeater receives a selected digital satellite radio channel from the content server via the Internet while not receiving unselected digital satellite radio channels, and wirelessly broadcasts the selected digital satellite radio channel in a different waveform as used by the terrestrial repeater but using a same physical layer. A digital satellite radio unit receives the selected digital satellite radio channel from the micro-repeater while not receiving the unselected digital satellite radio channels.
