Classification: CPC H | IPC H

Claim 13:
14. A radio frequency (RF) node for a mosaic network, comprising:
a wireless transceiver; and
processing circuitry coupled to the wireless transceiver and configured to:
estimate a channel and interference estimation;
calculate a closed form beamforming solution based on the channel and interference estimation for a first plurality of mosaic nodes to determine a first predistortion filter;
receive an RF signal at the wireless transceiver;
apply a predistortion filter to the RF signal to produce a retransmitted signal; and
retransmit the retransmitted signal such that the retransmitted signal coherently combines with one or more additional retransmitted signals to increase signal power in a direction of a receiving target, wherein the first predistortion filter causes the retransmitted signal to coherently combine at the receiving target such that the signal power is concentrated in the direction of the receiving target.
