摘要：
This study investigates the channel correlation of a multiple-input multiple-output (MIMO) system tiered with a femtocellular network─specifically, a MIMO- femtocell (MIMO- FT) system, Channel correlation degrades the overall system performance of a wireless communication systems. Furthermore, this study argues that the coverage area of a MIMO-FT deployment will be reduced in size by channel correlation occurring in propagation channel. This study utilizes some derived analytical closed-form formulas to discuss the phenomenon of channel correlation occurring in MIMO-FT systems. In addition, an algorithm with precoding is explored for the purpose of mitigating the effects of channel correlation.
