  • Patent number: 9748937
    Abstract: An important component in digital circuits is a phase rotator, which permits precise time-shifting (or equivalently, phase rotation) of a clock signal within a clock period. A digital phase rotator can access multiple discrete values of phase under digital control. Such a device can have application in digital clock synchronization circuits, and can also be used for a digital phase modulator that encodes a digital signal. A digital phase rotator has been implemented in superconducting integrated circuit technology, using rapid single-flux-quantum logic (RSFQ). This circuit can exhibit positive or negative phase shifts of a multi-phase clock. Arbitrary precision can be obtained by cascading a plurality of phase rotator stages. Such a circuit forms a phase-modulator that is the core of a direct digital synthesizer that can operate at multi-gigahertz radio frequencies.

    Abstract: A method of decoding a received SC-FDMA symbol in a receiver in a OFDM communication system is described. The method comprises calculating an approximate constellation energy {circumflex over (K)} from channel matrices Hi for all subcarriers i, a noise covariance matrix S, and a data signal power matrix C associated with the OFDM symbol, an approximate constellation energy {circumflex over (K)}. The approximate constellation energy {circumflex over (K)} is calculated according to: Q i = H i H ? S - 1 ? H i ; Q ^ = 1 N sc ? ? i = 0 N sc - 1 ? Q i ; K ^ = diag ? ( ( Q ^ + C - 1 ) - 1 ? Q ^ ) The method further comprises decoding the received symbol using at least the associated approximate constellation energy {circumflex over (K)}. Also, a receiver, an apparatus, an OFDM communication system and a computer program product for such decoding are described.

  • Patent number: 9302185
    Abstract: A method is provided for decision streams for synchronizing visual script language processing between networked computers. A master computing device may receive a remote kickoff stream indicating master nodes to be processed on a master graph, create a master decision stream using the remote kickoff stream, process master nodes of the master graph to populate the master decision stream with states and actions during the processing, and distribute the master decision stream to clients for synchronization of private graphs. The master and private graphs may be copies of the same visual script for implementing game logic, which may be created and edited using a graphical user interface (GUI). Nodes of the graphs can be marked as master, requiring global synchronization, or private, allowing immediate local processing with reduced latency. Thus, online game designers are empowered to balance the competing concerns of state synchronization and latency.

  • Patent number: 9226199
    Abstract: Systems and techniques for managing channel reservation in a full-duplex wireless network. A transmitting node sends a media access control frame to a receiving node, including an integrity check field in a header of the frame. Upon performing an integrity check and determining that the media access control frame is addressed to itself, the receiving node sends a transmission so as to reserve the channel. If the receiving node has no data to send, the transmission may be an acknowledgement field, and if the receiving node has data to send, the transmission may be a media access control frame including an integrity check field in a header of the frame.

  • Patent number: 9178635
    Abstract: Separation of sub-bands of communications signals to reduce interference in distributed antenna systems (DASs) is disclosed. A sub-band separation circuit coupled to a plurality of antennas is configured to distribute and receive and transmit a pair of downlink and uplink sub-band signals. The sub-band separation circuit is coupled to a duplexed port of a remote unit that distributes uplink communications signals to the DAS and receives downlink communications signals from the DAS. In order to isolate the downlink communications signals from the uplink communications path in the remote unit, the isolation circuit includes a plurality of sub-band isolation circuits. Each sub-band isolation circuit is configured to isolate at least one sub-band of the downlink communications signal to generate a downlink sub-band signal that has a desired frequency separation or gap with uplink communication signals received at the duplexed port.

  • Patent number: 9178727
    Abstract: A filter bank receiver (FBMC) effecting a carrier frequency offset compensation in the frequency domain. The receiver comprises an FFT module extended by the overlap factor (610), a module (630) offsetting a predetermined number of subcarriers at the output of the FFT followed by a filter for reducing interference between subcarriers (640), the number of subcarriers and the coefficients of the interference reduction filter being determined from an estimation () of the frequency offset. The vector of samples thus obtained is then the subject of channel equalisation (650) before being filtered by a battery of analysis filters and spectrally de-spread (660). Finally, after spectral de-spreading, the vector of samples is demodulated by an OQAM demodulation (670) so as to recover the transmitted data.

    Abstract: Systems and methods are presented for controlling the peak-to-average-power of a baseband orthogonal-frequency-domain multiplexing (OFDM) signal by designating a subset of the available subcarriers as information-bearing data-subcarriers, and loading remaining subcarriers by symbols that are a function of the symbols loading the data-subcarriers. At the receiver, the data-dependent subcarriers are optionally combined with data-subcarriers to increase error protection.

  • Patent number: 9094995
    Abstract: The present application relates to a method for enabling a terminal to transmit channel status information in a wireless communication system. Specifically, the method for enabling the terminal to transmit the channel status information in the wireless communication system includes the steps of: receiving a reference signal from a serving cell or an adjacent cell; determining the priority of the predetermined precoding matrix index (PMI) based on the reference signal; and transmitting the PMI together with a stacking flag to the serving cell according to the priority, wherein the number of PMI to be transmitted to the serving cell is determined based on a size of a buffer commonly set in the serving cell and the terminal, and the stacking flag indicates storing the PMI into the buffer or initializing the buffer.
