| Abstract(in English) | In time-varying fading environments, a channel prediction method should be used to reduce channel errors due to the channel changes between the transmit weight matrix determination time and the actual data transmission time, so that the performance of MIMO E-SDM (Eigenbeam-Space Division Multiplexing) system can be improved. Here, we present an experimental measurement setup to evaluate the performance in actual environments. Based on the measured data, simulation results show that by using our proposed prediction methods much better performance can be obtained in both actual line-of-sight (LOS) and non-LOS (NLOS) communications environments. We can also see that the performance in LOS environments is better than that in NLOS ones. |
