摘要：

Directional antenna elements were introduced while considering spatial fading correlation (SFC) and multiple input multiple output (MIMO) multi-antenna model of user terminal was studied on which based on statistical channel model and performance evaluation methods. Azimuth power spectrum (APS) model of arrival signal for user terminal was applied to MIMO channel modeling of Kronecker. With this MIMO channel model concept, the impact of directivity of antenna element on system performance in statistical channel model which included SFC coefficient, MIMO multi-path channel capacity and bit error ratio (BER) was analyzed. Simulation and optimization results show that the directivity of array element in MIMO multi-antenna model has a significant impact on system performance. Reasonable arrangement for beam direction of array elements can increase multi-path capacity by about 10% and reduce BER. ©, 2015, Huazhong University of Science and Technology. All right reserved.
