Patents by Inventor Arun Visvanathan

Arun Visvanathan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8937863
    Abstract: Systems and methods for controlling the flow of a wireless communication apparatus based on a plurality of resources. The levels of each of a plurality of resources are monitored and the flow state of the apparatus is set to ensure safe operation in view of disparate usage of the resources. In one embodiment an individual flow state is determined with respect to each resource. One of the individual flow states is then selected for the apparatus as a whole.
    Type: Grant

    Date of Patent: January 20, 2015
    Assignee: QUALCOMM Incorporated

  • Patent number: 8074158
    Abstract: To perform erasure detection for an intermittently active transport channel with unknown format, a receiver determines an energy metric and a symbol error rate (SER) for a received block with CRC failure. The receiver computes uncorrelated random variables u and v for the received block based on the energy metric and SER, the estimated means and standard deviations of the energy metric and SER, and a correlation coefficient indicative of the correlation between the energy metric and SER. The receiver then evaluates the uncorrelated random variables u and v based on at least one decision criterion and declares the received block to be an erased block or a DTX block based on the result of the evaluation. The decision criterion may be defined based on a target probability of false alarm and adjusted based on another metric, such as a zero state bit, for the received block.
