Claim 17:
18. A network node, comprising:
a processor circuitry;
a wireless transceiver coupled to the processor circuit; and
a memory coupled to the processor circuit, the memory comprising machine readable program instructions that, when executed by the processor circuit, cause 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.
