We have proposed Massive Antenna Systems for Wireless Entrance (MAS-WE) and verified its effectiveness through computer simulations and propagation experiment with circular array antenna. As the further extension, we newly proposed introducing parallelogram array antenna which can reduce channel vector correlation (inter-user correlation) without any processing load enlargement, and verified its effectiveness through computer simulations. This paper investigates improved spatial division multiplexing performance with parallelogram array antennas by using measured CSI. The proposed antenna configuration can provide stably lower inter-user correlation fluctuation over frequency domain and achieve 21 spatial division multiplexing with 63-element array. |
