MIMO system with antenna selection based on diversity theory can improve transmission characteristics. In this system, we have reported the effectivity of directional antenna for each transmission terminal but still not examined in detail about the antenna directivity configuration. In this paper, we examin transmission characteristics of 2×2 MIMO selected from 4×2 multi-anntena setup using unti-uniform directivity for transmission terminal by three dimensional (3-D) ray-tracing simulation of indoor propagation model. As a result, we show that the mean error rate of each transmittion stream is improved dramatically. We also explain simulation result from the distribution of eigenvalue of correlation matrix. |
