Comparison of 4amp;#x00D7;1 SIMO and 2amp;#x00D7;2 MIMO sensors based on measured propagation channels

摘要

High-speed transmission technologies using array signal processing such as Single Input Multiple Output/ Multiple Input Multiple Output (SIMO/MIMO) have been recently attracted much attention due to smart phones and wireless LAN systems. High data transmission can be realized by utilizing accurate channel state information (CSI). However, it is well known that the characteristic of SIMO/MIMO performance is severely degraded by variation of the propagation channel [1].
