IEEE/ICACT20210112 Question.4 Questioner: kawano.masahiro959@mail.kyutech.jp 2021-02-10 오후 3:42:09	IEEE/ICACT20210112 Answer.4 Answer by Auhor rusly.eic04g@nctu.edu.tw 2021-02-10 오후 3:42:09
Thank you for your very interesting presentation. My name is Kawano, and I am a student at Kyushu Institute of Technology. I have a question on page 8 of the slide. Q. In the figure on the right, I learned that when the tilt angle of the antenna is changed, the change in total power is large in Cpol-Cpol case and small in other cases. Which is preferable from the viewpoint of the degrees of freedom of MIMO? Thank you.	Hello, Kawano, nice to meet you and thank you for question. Crosspolarized antenna array would be preferrable for dof of MIMO, it has both good BER performance and smaller correlation between antennas
