In a multiple-input multiple-output (MIMO) precoding system based on finite-rate feedback, the receiver sends a precoding matrix to the transmitter via a feedback channel. The overall system performance is degraded due to feedback error. In this paper, we propose a robust feedback scheme that employs the index permutation technique to provide the system… CONTINUE READING
