  • Universal real-time interface for wireless modems
    Patent number: 8520723
    Abstract: The apparatus and methods described herein are used to provide data between an application and a modem. One method includes providing data in application data units from the application to the modem, transmitting the data from the modem to a receiver, and reporting by the modem to the application, whether each application data unit has been successfully transmitted from the modem to the receiver.
    Type: Grant
    Filed: December 9, 2010
    Date of Patent: August 27, 2013

    Inventors: Sundeep Rangan, Prashanth Hande, Niranjan N. Ratnakar, Ozge Koymen, Ritesh K. Madan, Atul Maharshi, Subhadeep P. Roy, Siddharth Ray
  • Apparatus and methods for providing a communication quality feedback of an end-to-end communication path
    Patent number: 8520699
    Abstract: The apparatus and methods described herein are used to provide a communication quality feedback of an end-to-end communication path between an application transmitter and an application receiver. One method includes transmitting data from the application transmitter to the application receiver via the end-to-end communication path, the end-to-end communication path having at least one wireless link with a wireless transmitter and a wireless receiver, generating, at the wireless transmitter, a first communication quality feedback message, and transmitting the first communication quality feedback message from the wireless transmitter to the application transmitter in a standardized format.

  • Simplified interference suppression in multi-antenna receivers
    Patent number: 8150345
    Abstract: A signal received via a plurality of antennas, and containing an interference component and a desired communication component, is processed to suppress the interference component. The interference component is suppressed based on an inverse of a spatial covariance matrix, which inverse is produced without performing a matrix inversion operation.
