Latest Patents

One of his latest patents is a method to improve ATSC-VSB transceiver performance employing a time-frequency waveform processor. This innovation provides a backward-compatible enhancement to ATSC-VSB transmissions, enabling intra-field channel estimation for better channel equalization. By inserting one or more time-frequency waveforms into the transmitted signal with systematic time and frequency variation synchronized to the currently available field sync, a coherent demodulator can directly estimate the channel frequency response. The power of the inserted waveform(s) is minimal compared to the existing 8-VSB signal, ensuring that existing receivers function as intended with only minimal degradation of performance.

Another significant patent is for a free-running numerically-controlled oscillator using complex multiplication with compensation for amplitude variation due to cumulative round-off errors. This method and apparatus efficiently generate complex sinusoids of a desired frequency by multiplying a phasor by a predetermined value once every sampling interval. The highest order bits within the phasor identify if it is at an integer multiple of 45 degrees, allowing for corrections to be made if necessary.
