  • Patent number: 9269127
    Abstract: A hybrid filtering method called Karhunen Loeve Transform-Wavelet (KW) filtering is presented to de-noise dynamic cardiac magnetic resonance images that simultaneously takes advantage of the intrinsic spatial and temporal redundancies of real-time cardiac cine. This filtering technique combines a temporal Karhunen-Loeve transform (KLT) and spatial adaptive wavelet filtering. KW filtering has four steps. The first is applying the KLT along the temporal direction, generating a series of “eigenimages”. The second is applying Marcenko-Pastur (MP) law to identify and discard the noise-only eigenimages. The third applying a 2-D spatial wavelet filter with adaptive threshold to each eigenimage to define the wavelet filter strength for each of the eigenimages based on the noise variance and standard deviation of the signal. Lastly, the inverse KLT is applied to the filtered eigenimages to generate a new series of cine images with reduced image noise.

  • Publication number: 20160049876
    Abstract: A synchronous rectifier comprising a discrete switching device and a controller for controlling the discrete switching device both mounted on a common die pad and packaged in a single package. The packaging of the discrete switching device and the controller together in a single package provides shortest path of connection between the ports of the controller and the switching device, enabling the controller to accurately sense voltage across the switching device thereby avoiding the effect of parasitic inductances and enabling the controller to enable/disable the switching device at the precise time, resulting in improved power consumption and better efficiency.

  • Patent number: 9225447
    Abstract: Disclosed are a method and a device for transmitting an aperiodic SRS in a TDD system. In the technical solution of the present invention, a symbol is defined for the transmission of the aperiodic SRS in a special subframe in the TDD system. This avoids a scenario in which the transmission position of the aperiodic SRS is undefined when a plurality of symbols that can be used to transmit the aperiodic SRS are available in an uplink pilot time slot (UpPTS). The problem of transmitting aperiodic SRS in a TDD system special subframe is thus solved. The modification to corresponding instruction messages is not extensive, and there is no overuse of system resources.

  • Publication number: 20150338487
    Abstract: A method for improving the signal-to-noise ratio (SNR) of TGRAPPA. The SNR of the ACS lines is proportional to the condition number of the GRAPPA kernel encoding equations. Therefore, the GRAPPA kernel estimated from higher SNR ACS lines amplifies the random noise in GRAPPA reconstruction. In TGRAPPA reconstruction of dynamic image series, a widely used method to acquire ACS lines is to average-all-frame (AAF). The present disclosure utilizes a tile-all-frame (TAF) as ACS lines to improve the SNR of the reconstructed images.

  • Publication number: 20150327256
    Abstract: The present invention discloses a method, system and device for determining a bandwidth of an uplink sounding reference signal SRS. The method for determining the bandwidth of the uplink SRS comprises the following steps: determining whether SRS is transmitted with the uplink pilot time slot if the SRS is transmitted with the largest bandwidth level; transmitting SRS with the non-extensive SRS bandwidth if SRS is determined to be transmitted with the uplink pilot time slot and the UE reaches the power limit. In the present invention, the signal-to-noise ratio detected on the bandwidth with which SRS transmitted can be maintained, and the accurate detection of the channel information is thereby realized.

  • Patent number: 9007132
    Abstract: An oscillation signal generator includes a quadrature voltage-controlled oscillator (QVCO), a phase corrector and a frequency adjusting circuit. The QVCO provides multiple oscillation signals having difference phases. The phase corrector selects one of the oscillation signals as a first oscillation signal and outputs the first oscillation signal from a first output terminal, and selects one of the oscillation signals as a second oscillation signal and outputs the second oscillation signal from a second output terminal. A phase difference between the first and second oscillation signals satisfies a predetermined relationship. The frequency adjusting circuit is coupled to the phase corrector, and generates a quadrature signal and an in-phase signal according to the oscillation signals. The frequency of the oscillation signals is a non-integral multiple of the frequencies of the quadrature and in-phase signals.

  • Publication number: 20150085774
    Abstract: Disclosed are a response information transmission method, system and device. A base station can configure at least two PUCCH transmission carriers for user equipment, accordingly, the user equipment can select at least one PUCCH transmission carrier from the at least two PUCCH transmission carriers which are configured by the base station to transmit response information fed back on a corresponding subframe, and accordingly, the base station can receive the response information which is fed back by the user equipment on at least one PUCCH transmission carrier.
