Abstract :
In multiple-input multiple-output (MIMO) systems, eigenbeam space division multiplexing (E-SDM) has a higher performance compared to conventional SDM and has an advantage that simple detection algorithms are available at a receiver. However, the transmitter requires MIMO channel information. If it has an error, the performance degradation is inevitable. In this paper, we propose a compensation way against channel information error due to temporal channel transition. The effect is also numerically analyzed.
