Abstract :
In this paper, the performance of 60 GHz MIMO system is analyzed based on experimental data. The mutual information (MI) of the measured channel is compared to the MI of an iid MIMO Rayleigh channel. It is seen that the mean MI of the channels are quite close to each other. Then, the MI of the MIMO system is compared to the one of a MIMO system with antenna selection. It is found that, when considering switching networks with realistic losses, the performance decreases drastically and, in most cases, MIMO antenna selection leads to lower MI than traditional MIMO with the same number of RF chains. Finally, the achievable data-rate of a realistic 4 times 4 MIMO system is calculated, based on the experimental data. It is shown that with 500 MHz bandwidth such a system can provide multigigabit communications at distance up to 10 m.
