Indoor Experimental Evaluation of Collaborative Interference Cancellation Technique in Multi-user MIMO Transmission
Ryo Shinohara, Hidekazu Murata (Kyoto Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Multi-user multiple-input multiple-output (MU-MIMO) transmission has been investigated to improve the spectrum efficiency in wireless communications.
Outdated CSI causes residual inter-user interference on precoding for MU-MIMO.
Sufficient interference rejection by linear signal processing requires more than the number of antennas which mobile stations can equip.
In this paper, collaborative interference cancellation is proposed to cancel inter-user interference.
In this scheme, to increase the number of receiver antennas, mobile stations share their received signals collaboratively by using short-range wireless interface.
Experimental results show BER improvement by mobile stations' antennas at intervals of 1 meter.
