Abstract
A radio repeater system may include: a multiple input multiple output (MIMO) donor antenna configured to transmit/receive MIMO signals to/from base stations; a beamforming control unit configured to control beamforming by adaptively applying a phase weight to the repeated signals received from the MIMO donor antenna; an interference signal cancellation unit configured to estimate and analyze feedback interference signals introduced from a MIMO service antenna to the MIMO donor antenna and adaptively cancel the feedback interference signals; and the MIMO service antenna configured to transmit/receive MIMO signals to/from radio terminals in a service area.
