Classification: CPC H | IPC H

Claim 0:
1. A base station, comprising:
a transceiver configured to:
recover a first recovered transport stream based upon receiving a first transport stream of an uplink (UL)-multiple-input and multiple-output (MIMO) transmission and a second transport stream of the UL-MIMO transmission, wherein the first transport stream and the second transport stream propagate through a first signal pathway of a radio link, and
recover a second recovered transport stream based upon receiving the first transport stream and the second transport stream, wherein the first transport stream and the second transport stream propagate through a second signal pathway of the radio link; and

a processor, coupled to the transceiver, configured to:
de-map the first recovered transport stream and the second recovered transport stream to provide a first transport layer and a second transport layer,
determine a first signal metric of the first transport layer and a second signal metric of the second transport layer,
inject noise into the first transport layer based on the first signal metric being greater than or equal to the second signal metric to lessen an imbalance between the first transport stream and the second transport stream, and
inject the noise into the second transport layer based on the first signal metric being less than the second signal metric to lessen the imbalance between the first transport stream and the second transport stream.
