In MIMO Eigenbeam Space Division Multiplexing (E-SDM), it is already reported that increased velocity of phase angle variation because the transmission and the receiving weights become more sensitive for smaller gap between eigenvalues. In this report, effects of close eigenvalues were evaluated by number of antenna elements and spatial correlations. The evaluation is executed by using ITU-R M.2135-1 time variant channel model. As a result, it is suggested that there is a good possibility of improvement in communication performance in MIMO E-SDM by an adaptive control of channel estimate time period that has eigenvalues gap as an input parameter. |
