Latest Patents

One of his latest patents is the "Multi-tone transceiver system using two steps of DMT-CMFB." This invention presents a wideband multi-tone transceiver system that is interoperable with Asymmetric Digital Subscriber Line (ADSL) transceiver systems. It features a two-step transceiver system that incorporates a discrete multi-tone transceiver system and a cosine modulated filter bank (CMFB) transmultiplexer. The design minimizes interference between sub-bands, ensuring a physically transparent transmission channel for each sub-band signal. This innovative approach allows for a simpler structure and significantly reduces circuit size by sharing the FFT function across sub-channels.

Another significant patent is the "Time-domain equalizer of cascaded filters for VDSL." This method focuses on designing Time-domain Equalizers (TEQs) for different signal bands in a VDSL transmission system. The process involves dividing the entire signal band into at least two segments, modulating them separately before transmission, and applying an algorithm to reduce channel response lengths at the receiver. This design not only reduces hardware requirements but also ensures compatibility with existing ADSL transmission systems.
