Latest Patents
One of his latest patents is an "Adaptive demodulation method and apparatus using an artificial neural network to improve data recovery in high-speed channels." This invention utilizes a neural network demodulator within a receiver to provide Inter Symbol Interference (ISI) channel equalization and correct for I/Q/phase imbalance. The neural network is trained with a single integrated training step, allowing it to simultaneously address channel impairments, which is a significant advancement over prior methods that handled each impairment separately.
Another notable patent is the "Use of neural network based matched filter for fast response time in high-speed communications channels." This technology employs a neural network within a receiver to discriminate a large set of input waveforms without relying on a vast array of conventional matched filters. The neural network is trained under actual line conditions, enabling it to work effectively with finite waveforms based on digital modulation principles. This system allows for fast processing and is particularly suitable for high-speed data communications systems.
