Latest Patents

One of his latest patents is titled "Method and apparatus for rate conversion." This invention focuses on a method and apparatus in a radio telecommunications system for converting data from a first sample rate to a second sample rate. The first and second sample rates are preferably within 10% of each other. An input buffer receives a plurality of data groupings at a first sample rate. A spline filter utilizes the input data along with a phase difference between input and output data to calculate a third order spline function and an output time for the input data. This information is used to convert the input data at the first sample rate to output data at a second sample rate. The output data is buffered within an output buffer until transmitted to an associated base band unit.

Another significant patent is "Filter with feed-forward AGC." This device and method are designed to fully realize the precision gained internally from a conventional digital signal processor by generating a feed forward automatic gain control (AGC) signal. The feed forward AGC bit indicates the output of the digital signal processor being multiplied by a gain factor when the output from the digital filter included in the digital signal processor is below a threshold value. When the feed forward AGC signal is received by an inphase and quadrature (I/Q)-to-(logR/.phi.) converter connected to the digital signal processor, a corresponding value is subtracted from the radius component of the signal calculated by the (I/Q)-to-(logR/.phi.) converter. This innovation allows a digital signal processor with fewer IO bits than is nominally required for the precision and dynamic range of the output signal to be implemented.
