Abstract: A system and method are provided for calibrating for an I/Q mismatch of a direct conversion receiver based on a random signal having a two-dimensional I versus Q trajectory, such as radio frequency (RF) noise. In general, the random signal is received and downconverted to a quadrature baseband signal having an in-phase component and a quadrature component. The variance of the in-phase component, the variance of the quadrature component, and the covariance of the in-phase component with the quadrature component are computed based on samples of the quadrature baseband signal. A correction matrix used to compensate for the I/Q mismatch of the receiver and/or I/Q mismatch including a gain mismatch and a phase mismatch of the receiver is then computed based on the variance of the in-phase component, the variance of the quadrature component, and the covariance of the in-phase component with the quadrature component.

Abstract: The invention describes a method of efficient way of video delivery in the legacy (non-802.11e) infrastructure networks and a device (Transmitter) based on this method. The invention permits the video stream to bypass the access point and therefore increases the available bandwidth by a factor of two or more and permits increasing the throughput by improving only the radio and antenna on the Transmitter (as opposed to improvements on both the Transmitter and AP necessary without the invention).

Abstract: A computing device may be configured to communicate with an enterprise network. A computer file may be generated from a remote resource for purpose of enabling configurations needed by the computing device to be pre-specified. The computer file may include a plurality of configuration items that are to be used with a network setup application, which is to be operated on the computing device. On the computing device, the network setup application is executable to enable connectivity between that computing device and the enterprise network through one or more network access points of the enterprise network. Once generated, the computer file can be transferred to the computing device. The network setup application may programmatically incorporate the configuration items of the computer file in its setup procedure for establishing connectivity between the computing device and one or more network access points.

Abstract: A small-size magnetoresistive device which allows measurement of spatial distribution of magnetic field along one axis with high resolution is disclosed. The magnetoresistive device includes: a magnetoresistive stripe oriented along the measurement axis; a plurality of conductive layers comprising electrodes distributed along the length of the stripe, separated by insulating layers. The measurement of the spatial distribution of the magnetic field is performed by analyzing signal levels between electrodes.
