| Abstract(in English) | Massive MIMO enables the improvement on the transmission rate without increasing the burden on the signal processing by employing a large number of antennas at a base station. The authors have evaluated the effectiveness of the massive MIMO in small cell environment. In this report, we evaluated the quantitative characteristics of the interference rejection when the base station by massive MIMO transmission is located on the rooftop of the building in an actual microcell environment. On the rooftop of the building, the circular cell is required to create the omni-directional area. Hence, we use the circular based massive array antennas. Moreover, we verify the effectiveness of the interference rejection while reducing amount of calculation when using the hybrid algorithm which employs the maximum ratio combining (MRC) on the analog part and zero forcing (ZF) in the digital processing part. |
