Abstract
The present invention relates to a method for antenna calibration in a communication system having a Bandwidth divided into multiple frequency intervals M with multiple communication units, each comprising communication circuitryconnected to an antenna arrangement, communicating with each other over multiple communication channels. The method comprises: establishing a calibration sequence to perform antenna calibration for at least one of said multiple frequency intervals; converting the calibration sequence from the frequency domain to the time domain; transmitting a part of said calibration sequence in the time domain from a first communication circuitryto a second communication circuitryover the multiple communication channels; receiving the part of said calibration sequence in the second communication circuitryfor each communication channel; performing antenna calibration based on the received part of the calibration sequence.
