Latest Patents
One of Donnet's latest patents is titled "Method and device for anti-interference fighting in a telecommunications system." This invention addresses the challenge of interference in frequency-hopping communication systems. The system utilizes at least one main sensor and several auxiliary sensors to receive frequency-hopping signals. These signals are organized to include useful bands and guard bands, with a specific ratio determined by the probability of interference interception. The invention selects signals from the guard bands that exceed a predetermined signal level and applies spatial-filtering weightings based on a correlation matrix of noise and jammers. This process effectively filters the baseband signals of the received frequency-hopping signals.
Another significant patent by Donnet is the "Method and device for the calibration-equalization of a reception system." This invention involves a device and method for calibrating and equalizing reception chains in an antenna processing system. It includes multiple RF chains linked to radiating elements, a set of sensors formed from the outputs of these RF chains, and a channel for injecting calibration signals. The device is equipped with a processor to manage its components, along with mechanisms to adjust the gain of RF chains and minimize directivity toward interference sources.
