Latest Patents

Among his latest patents is the groundbreaking "Discrete Multi-Tone Systems for Half-Duplex IP Links." This invention revolves around a DMT system designed for a half-duplex two-way link, which transmits Internet Protocol encoded video streams over a coaxial cable alongside a baseband rendition of the same stream. The technology employs a plurality of downlink symbols that are modulated on subbands of subcarriers within the downlink signal. These symbols encode data on subbands using constellations of Quadrature Amplitude Modulation (QAM), with different subbands potentially utilizing varying QAM constellations. Notably, lower-order constellations are assigned to subbands containing higher-frequency subcarriers, while higher-order constellations are allocated to those with lower-frequency subcarriers. A block error correction decoder in the system is synchronized based on the identification of the first constellation of QAM symbols alongside information delineating the boundaries between the plurality of downlink symbols. This advancement represents a significant step forward in the efficiency of video data transmission.
