Bob D. Nuckolls 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).

  • Spectrum sensing engine
    Patent number: 8537223
    Abstract: Systems, methods, and devices for reducing interference with digital television transmissions occurring over a bandwidth are disclosed. The digital television signal is correlated to a reference digital television field sync signal. A non-coherent correlation power measurement is determined based on the correlation of the received digital television signal to the reference digital television field sync signal. A plurality of maximum non-coherent correlation power measurements are determined over multiple field times. An energy estimate for the digital television transmission is determined based on the maximum non-coherent correlation power measurements. A transmit mask filter is generated based on the energy estimate. The transmit mask is applied to transmissions to reduce interference with detected digital television transmissions.
