Claim 19:
20. A computer program product comprising a non-transitory storage medium including program code to be executed by processing circuitry of a network node configured to operate in a communication network, whereby execution of the program code causes the network node to perform operations comprising:
repeating operations of:
transmitting a slice of a fountain coded sequence through the plurality of antenna branches to the respective antenna elements; and
for each antenna branch of the plurality of antenna branches:
selecting the transmitted slice as a feedback signal through a return path; and
determining a signal quality of the feedback signal;

until the signal quality of the feedback signal for each antenna branch is greater than a threshold level; and
performing antenna calibration based on the feedback signal for each antenna branch.
