Title
Experimental comparison of linear prediction schemes for multi-user MIMO systems
Abstract
In a multi-user multiple-input multiple-output (MU-MIMO) system, zero-forcing precoding can completely eliminates inter-user interference when the perfect channel state information is available at the base station. However, in time-varying channels, the transmission performance of MU-MIMO systems is severely degraded due to inter-user interference. In this paper, channel prediction is employed for channel tracking, and in-lab experiments are carried out to confirm its performance. The bit error rate (BER) performance is measured and compared with the computer simulation results. Both in-lab experiments and the computer simulations show that channel prediction improves the BER performance.
