Latest Patents
One of her latest patents is titled "Apparatus and method for hybrid traffic and pilot signal quality determination of finger lock status of rake receiver correlators." This invention provides improved systems and methods for spread spectrum communication. It employs hybrid Eb/No and pilot-based finger lock determination for RAKE receivers. The technology periodically sets finger lock thresholds using an extended time-averaged Eb/No traffic signal estimate for each finger mapped to an Ec/No pilot level. This innovative approach decreases the required Ec/No level when the Eb/No estimate increases and increases the required Ec/No level when the Eb/No estimate decreases. Additionally, when pilot signals are weak but traffic signals remain strong, fingers will remain locked to enhance the combiner output signal-to-noise ratio.
Another notable patent is a "Variable bit rate coder, and associated method, for a communication station operable in a communication system." This invention focuses on encoding frames of speech generated during the operation of a communication station in a cellular communication system. The selection of the coding rate is responsive to actual coding performance at multiple coding rates, ensuring optimal performance.
