Abstract:
1. A method for selecting antennas to communicate a packet in a network, wherein the network includes a transmitter and a receiver, wherein the transmitter includes a set of transmit antennas and the receiver includes a set of receive antennas, comprising the steps of: duplicating, in the transmitter, the packet as copies of the packet; selecting, in the transmitter, subsets of the set of transmit antennas independent of channel characteristics between the subsets of transmit antennas and the set of receive antennas, wherein combinations of the antennas in the subsets of the transmit antennas are different; selecting, in the receiver, subsets of the set of receive antennas independent of channel characteristics between the subsets of receive antennas and the set of transmit antennas, wherein combinations of the antennas in the subsets of the receive antennas are different; transmitting, by the transmitter, each copy of the packet without receiving a feedback from the receiver; and transmitting, by the transmitter, each copy of the packet from the transmitter to the receiver using a different frame and a different subset of the antennas for each frame and each copy of the packet, while the receiver uses a single subset of the receive antennas to receive the copies of the packet, wherein the frames are temporally disjoint in time to reduce overhead and delay in the network.
