On the performance of MIMO E-SDM systems with channel prediction in indoor time-varying fading environments

Multiple Input Multiple Output (MIMO) systems using an eigenbeam-space division multiplexing (E-SDM) technique have been recently considered high-rate wireless communications. In the E- SDM technique, channel state information (CSI) is required at a transmitter in order to form orthogonal transmission beams and allocate transmit data resources adaptively. In the ideal case, received signals can be detected without inter-substream interference, therefore very high performance is obtained.
