  • Measuring received signal quality
    Patent number: 8364140
    Abstract: A method of determining a signal quality parameter in a radio communications device includes: measuring a signal error parameter of a received signal (104); comparing said measured signal error parameter to a threshold level (106), and determining the signal quality parameter on the basis of a reference signal error parameter value (114) in the event that the measured signal error parameter value is less than the threshold level (112).

  • Computing filter coefficients for an equalizer in a communication receiver
    Patent number: 7987220
    Abstract: The present invention provides an equalizer (200) and a method for computing equalizer filter coefficients in a communication receiver. The equalizer filter coefficients are computed on the basis of a real matrix T which is generated from channel estimation vector f, which is derived from the channel estimation inputs.

  • Cell search method and apparatus in a WCDMA system
    Patent number: 7366141
    Abstract: A cell search method for use in a mobile communication system, the method including: performing one or more identification steps for identifying timing and codes of oversampled input signals; and reducing the resolution of the oversampled input signals before performing the one or more identification steps.

  • Apparatus, system, and method for presenting a document image together with a manual signature
    Publication number: 20050289059
    Abstract: An apparatus, system, and method are provided for presenting a document image together with a manual signature. The document image is of a traditionally paper-based transaction document such as a check. The invention includes an imager, a display device, and a controller. The imager generates a document image from a physical document. The display device displays the document image to a user. The controller associates a manual signature generated by the user with the displayed document image. An electronic representation of the manual signature may be generated using a digitizer in communication with the controller. Preferably, the components of the invention are implemented using multipurpose devices such as a touch-screen display, printer/scanner, and the like.
