OVER-THE-AIR BASED ESTIMATION OF PHASE ACCURACY OF A RADIO TRANSCEIVER DEVICE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18023013 Titled 'OVER-THE-AIR BASED ESTIMATION OF PHASE ACCURACY OF A RADIO TRANSCEIVER DEVICE'
Simplified Explanation
This abstract describes a method for estimating the phase accuracy of a radio transceiver device using over-the-air (OTA) measurements. The method involves obtaining phase relation estimates between different branches of the transceiver device for each position of a second transceiver device relative to the first device. These estimates are obtained from wireless signal measurements between the two devices. The method then calculates an average phase relation for a pair of transceiver branches by averaging the obtained estimates over all positions. This average phase relation represents the phase accuracy of the first transceiver device.
Original Abstract Submitted
There is provided mechanisms for OTA based estimation of phase accuracy of a first radio transceiver device. A method is performed by a controller. The method comprises obtaining, per each position in a sequence of positions of a second radio transceiver device relative the first radio transceiver device, a phase relation estimate between transceiver branches of the first radio transceiver device. Each phase relation estimate is obtained from measurements on a signal wirelessly transmitted between the first radio transceiver device and the second radio transceiver device. The method comprises estimating an average phase relation for at least one pair of the transceiver branches of the first radio transceiver device by averaging the obtained phase relation estimates over all the positions in the sequence of positions. The phase accuracy of the first radio transceiver device is represented by the average phase relation for the at least one pair of the transceiver branches.
