Latest Patents
One of his latest patents is titled "Methods and apparatus for spread spectrum modulation and demodulation." This invention relates to a method and an apparatus for spread spectrum modulation and demodulation using a special spread spectrum sequence. It is characterized by the modulation of Golay complementary codes onto orthogonal channels, resulting in a corresponding complex complementary code. The signal spread by this complex complementary code exhibits a low peak-to-average power ratio, along with sound self-correlation and cross-correlation properties. This innovation effectively addresses multi-access interference, thereby enhancing the overall communication performance of the system.
Another notable patent is the "Mains phase detection apparatus." This invention involves an apparatus designed for accurately detecting a mains phase. It consists of a zero-crossing detector, a digital phase detector, a digital loop filter, and a digital controlled oscillator (DCO) in a direct digital synthesized (DDS) manner. The apparatus employs an all-digital loop architecture and a high sampling clock to recover a signal that is phase orthogonal to the mains signal, maintaining the same frequency. The recovered signal experiences jitters of less than 10 microseconds. This apparatus is capable of implementing signal tracking with zero frequency error and zero phase across a wide range, providing excellent performance for power line carrier communication and mains frequency detection.
