Method for obtaining calibration parameters in one and the antenna array at least

摘要

How to obtain the calibration parameter for at least one antenna array are shown. The antenna array, and a radio module of the first and second having an antenna that accompanies each radio module both have either a calibration receiver selectively connectable to the main transmitter, Alternatively, both radio modules includes a calibration transmitter selectively connectable to the main transmitter. The method includes the step of injecting a calibration signal at a first radio module of the first, measuring the response to the first calibration signal to the first wireless module in the first. The measurement and the injection is executed repeatedly for all combinations of the wireless module and the second first. Calibration parameters are calculated based on the numerical Finally, the calculated numerical values ​​by using the response and these were calculated the. In addition, an antenna array that corresponds, and computer programs, and computer program product are shown.
