Compensation of Channel Information Error using First Order Extrapolation in Eigenbeam Space Division Multiplexing (E-SDM)
Abstract
In multiple-input multiple-output (MIMO) systems, eigenbeam space division multiplexing (E-SDM) [1], [2] has higher performance compared to conventional SDM and 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. Also, the effect is numerically analyzed.
