| Abstract(in English) | In actual cellular systems, base station (BS) may not be located in the cell center because of physical restrictions. This report investigates, assuming such a situation, the effectiveness of BS cooperation (BSC) in MIMO (multiple input multiple output) cellular system under irregular cell geometry. The cell shapes are determined by BS position based on Voronoi diagram, namely, UTs (user terminals) communicate the nearest BS. The influence of BS displacement is evaluated for several patterns using typical spatial processing algorithms. Through computer simulations, it is demonstrated that the BSC is effective under this situation, and how the BS displacement affects the system performance. |
