Abstract

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. Even if the interference cancellation techniques are not employed, the interference signal can be mitigated thanks to a narrow beam by the massive MIMO transmission. In this paper, an actual propagation channel was measured by using a wideband channel sounder with 96 elements in 2 GHz band at small cell environment. Moreover, we verify the effectiveness of the interference rejection when using antenna sector selection.
