  • Patent number: 10313163
    Abstract: A device includes circuitry configured to determine feedforward and feedback coefficients for an adaptive frequency-domain decision feedback equalizer (AFD-DFE) based on previously received signals. The equalizer output is determined by applying the feedforward and feedback coefficients of the AFD-DFE to a received signal, and the feedforward and feedback coefficients of the AFD-DFE are updated based on the equalizer output.

  • Publication number: 20190140874
    Abstract: A method and apparatus for equalization in a communication system. The method includes receiving an input of a block of symbols, filtering the input in the frequency domain, calculating an error factor in the time domain based on the filtered input, updating tap weights of the equalizer in the frequency domain using circular correlation based on the error factor and the conjugate of the input in the frequency domain, and outputting the filtered input.

  • Patent number: 9614699
    Abstract: Methods and apparatuses are provided for channel equalization in a communication system. The method includes initializing, using processing circuitry, filter coefficients of an adaptive decision feedback equalizer randomly in a predetermined search space. Further, the method includes updating, using the processing circuitry, the filter coefficients. The filter coefficients are updated using a least mean square recursion when the filter coefficients are stagnant. The filter coefficients are updated using a particle swarm optimization procedure when the filter coefficients are not stagnant. Further, the updating step is repeated until a predetermined stopping criteria is met. Further, the method includes, filtering, using the processing circuitry, a received signal using the filter coefficients.

  • Patent number: 9337999
    Abstract: A system for application usage continuum across client devices and platforms includes a first client device configured to execute a first instance of an application and a second client device configured to execute a second instance of the application. The first client device is configured to receive an indication to transfer operation of the first instance of the application running on the first client device to the second instance of the application on the second client device. The first client device is further configured to generate state information and data associated with execution of the first instance of the application on the first client device and cause the state information to be sent to the second client device to enable the second instance of the application on the second client device to continue operation of the application on the second client device using the state information from the first client device.
