Self-interference cancellation method based on V-BLAST in MIMO systems

Demands of Wireless repeater which is established, and easy to maintenance and repair are rapidly increased for extension of mobile communication system service [l]. Wireless repeater is amplifying signal that transmitted from base-station and transmit to mobile. This process makes feed-back interference. It eventually occur oscillation. In this paper, we propose feedback interference cancellation method based on V-BLAST in MIMO systems. This method removes the feedback channel using V-BLAST architecture.
