Abstract
Multiple-input multiple-output (MIMO) wireless systems obtain large diversity and capacity gains by employing multiple antennas at both the transmitter and receiver side. Proposed is a simple precoded closed-loop MIMO-OFDM system that improves the bit error performance. The proposed scheme only needs a feedback of two bits per OFDM tone for the entire duration of a frame.
