Latest Patents
One of his latest patents is titled "Dynamic rate adaptation methods in a vectored G.fast system." This patent describes various mechanisms, systems, methods, techniques, and devices for dynamic rate adaptation in a vectored G.fast (G.9701) system. A first communication device may perform estimation of a residual noise to derive signal-to-noise ratio (SNR) loss for each carrier of one or more carriers with respect to a transmitting port of the first communication device. The residual noise may be an increased noise expected to be experienced by a second communication device when one or more other ports in a vectored group of a plurality of ports of the first communication device are switched off. The first communication device may adapt to the residual noise during time slots of one or more downstream symbol positions where the one or more other ports in the vectored group are switched off by dynamically changing bit-loading.
Another significant patent is "Dynamic bandwidth allocation in OFDM communication systems." This patent provides various embodiments of a mechanism for dynamic allocation of bandplan. In one aspect, a communication device utilizes a bandplan during initialization in a digital communication system. The communication device modifies the bandplan after one or more channel estimations to optimize data rates of communications in both downstream and upstream directions.
