  • Publication number: 20140095755
    Abstract: An Adaptive Channel Selection (ACS) system is disclosed. A computing device uses wireless docking to provide a separate monitor and full-size input devices. The computing device requests docking, receives data wirelessly from the full-size input devices, and provides compressed video display data wirelessly for display on the separate monitor. An adaptive docking adapter receives and decodes compressed video display data and provides the decoded compressed video display data to a separate monitor for display. A wireless connection is disposed between the computing device and the adaptive docking adapter to provide wireless transmission of signals between the computing device and the adaptive docking adapter.

  • Patent number: 8275028
    Abstract: A computer system may comprise a receiver to perform equalization. The receiver comprises an equalizer. The equalizer may determine locations of a principal tap, a platform noise tap, and a pre-cursor tap in a feedforward path of an equalizer. Also, the equalizer may determine locations of a post-cursor tap, a cross-term tap, and a portable tap in a feedback path of the equalizer. The receiver may align the portable tap in the feedback path with the principal tap in the feedforward path. The platform noise tap may cancel the effect of platform noise on a principal located at the principal tap, thus enabling the computer system to operate effectively in severe platform noise environment. Also, the computer system may operate in statics and portable environment in which platform noise and AGWN may be present.

  • Patent number: 8085859
    Abstract: In one embodiment of the invention, a Fourier transform unit converts unsynchronized data received through multiple antennas to a frequency domain. Also, a spectrum estimation unit determines a power spectrum for the unsynchronized data. A notch filter removes data within a frequency band from additional unsynchronized data based on the power spectrum. A synchronization unit synchronizes the notch filtered data and a noise estimation unit determines a noise covariance matrix between the synchronized data received from multiple antennas. In addition, an equalization unit performs channel equalization on the synchronized data based on the noise covariance matrix.
