ABSTRACT:
A transmitter including a plurality of transmitting antennas and a processor operably coupled to the plurality of transmitting antennas. The processor is configured to select a first antenna from the plurality of transmitting antennas for transmission of a frame of data, determine if the frame is successfully received by a receiver, and select a second antenna different than the first antenna from the plurality of transmitting antennas for retransmission of the frame if it is determined that the frame was not successfully received by the receiver. The processor is configured to select a different antenna than a previous antenna for retransmission of the frame each time it is determined that the frame was not successfully received by the receiver. The processor is configured to discard the frame from further transmission if it is determined that the frame was not successfully received by the receiver after a number of transmission attempts.
