Latest Patents

Heikkinen's latest patents include innovative methods for antenna system calibration and interference reduction. The antenna system calibration patent discloses a method that involves driving calibration signals for antenna array beam calibration to an antenna array feeder line in a transceiver front end unit. This method utilizes one or more directional couplers and/or radio frequency probes, integrating calibration signal paths within the transceiver front end unit. Measurements are conducted on the calibration signals between different antenna combinations inside the antenna array. Based on the collected measurement data, calibration information is calculated for each measurement branch of the antenna array using a mathematical formula. Active antenna array beam calibration is then performed based on the calculated calibration information.

The interference reduction patent provides a method that includes obtaining antenna sensing information regarding signals received by a base station operating under a shared access system. This system allows a licensee to utilize a portion of the shared access spectrum that is currently unused by an incumbent system. The method detects when at least one device of the incumbent system is communicating on the shared access spectrum within the coverage area of the base station. It identifies the angular sector in which the device is located and dynamically isolates that sector from usage by the licensee system.
