Performance evaluation by antenna selection using real propagation channel on massive MIMO

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.
