|---|---|---|
Recently, Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has attracted much attention as a technology achieving high-speed wireless transmission with a limited bandwidth. However, since bit loading and adaptive modulation per sub-carrier should be employed according to the transmission quality of each sub-carrier in MIMO-OFDM, it is very important to understand the frequency correlation characteristics in broadband MIMO channels. This paper investigates the frequency correlation characteristics based on the antenna configuration for actual indoor MIMO channels. The results show that the frequency correlation of the channel capacity for the array antenna configured in the horizontal plane is significantly different compared to that configured in the vertical plane. Moreover, we propose a new cluster model that considers the antenna configuration in both the horizontal and vertical planes to estimate the frequency correlation in broadband MIMO channels. |
