Abstract :
We have investigated experimentally the effect of the strongest multipath component on the achievable LOS/NLOS MIMO capacity in an indoor environment. Our results demonstrate the effect of the contribution of the strongest component on indoor MIMO capacity. The contribution of the strongest multipath component is represented by the Rician K factor. The LOS component is indeed detrimental for an indoor MIMO system to achieve high throughput due to the increased spatial correlation of the MIMO channel. In addition, the measured MIMO capacities are all less than that of the ideal uncorrelated i.i.d channels. The indoor MIMO capacity increases with the decrease in the Rician K factor.
