| Abstract | Multiple-Input Multiple-Output (MIMO) wireless communication technology is expected to improve the channel capacity over the limited bandwidth of ex-isting networks. Since urban MIMO systems have complex propagation characteristics, the channel ca-pacity cannot be estimated using a simple method. Hence, we introduce channel capacity characteristics to urban MIMO systems by using a combination of imaging and ray-launching methods as a ray-tracing scheme. A simulation based on these methods with variable parameters can reproducibly estimate vari-ous urban propagation characteristics and discrimi-nate the effects of the urban model and antenna con-figurations. The characteristics of the Signal-to-Noise Ratio (SNR), the channel capacity, the spatial corre-lation, as well as the path visibility are then deter-mined from the results of the simulation. The pa-rameter called path visibility introduced in our previ-ous study is considered again herein. We clarify that only this single parameter can be used to determine the channel capacity characteristics in urban MIMO scenarios. This parameter also provides guidance in determining the appropriate range for the base sta-tion (BS) height. |
