Multiplexing efficiency of multiple antenna systems

In English Multiplexing efficiency is proposed as a simple and intuitive metric for characterizing multiple antenna systems in the spatial multiplexing mode of operation. Instead of comparing channel capacities of MIMO systems with different antennas, the metric offers valuable insights into the impact of antenna efficiency, efficiency imbalance and correlation on multiplexing performance. It is particularly useful in antenna design with the goal to achieve the optimum MIMO system performance. Experimental results involving mobile terminal prototypes highlight the effectiveness of the proposal.
