Latest Patents
Lyon's latest patents include a method and apparatus for transmitting and receiving digital data over a bandpass channel. This invention focuses on high data transmission rates by applying combined amplitude and phase modulation, specifically quadrature amplitude modulation, to digital data. The sampled digital waveform is converted to an analog waveform for transmission over bandpass channels, which have a limited range of frequencies. The sample rate is strategically chosen as an integer multiple of the symbol rate and carrier frequency to minimize processing overhead. The reception process mirrors the transmission, involving analogous amplitude and phase demodulation. This technique is particularly applied in oil well-logging applications, enabling efficient data transmission from downhole logging instruments over logging cables.
