Abstract :
A novel closed-loop MIMO architecture is proposed, in which channel state information is fully utilised to maximise channel capacity. Simulation results show that compared with V-BLAST, it can achieve much better performance while maintaining the same high spectral efficiency. Nearly 5 dB gain can be provided by this new architecture over V-BLAST.
