Title: François Dehmas: Innovator in LPWA Network Technologies
Introduction
François Dehmas is a notable inventor based in Meylan, France. He has made significant contributions to the field of low-power wide-area (LPWA) networks, with a focus on distance estimation methods and signal characteristics. With a total of 6 patents to his name, Dehmas continues to push the boundaries of innovation in telecommunications.
Latest Patents
One of his latest patents is a distance estimation method in an LPWA network. This invention relates to a method for estimating the distance between nodes in such a network. The process involves the first and second nodes transmitting narrow band signals at various carrier frequencies. These nodes receive and demodulate the signals into baseband signals, from which complex values are derived. These values are then processed by a trained neural network to estimate the distance between the nodes. Another significant patent involves a method for estimating characteristics of an impulse radio ultra-wideband signal transmitted by multiple antennas. This method includes steps for receiving and digitizing the signal, computing products of multiplication for each symbol, and estimating phase errors to determine reference phases.
