摘要： A full duplex multiple-input-multiple-output radio unit is provided. It comprises a transmission unit, an antenna unit, a reception unit, a circulator unit, and a power reduction unit. The transmission unit generates first signals. The circulator unit provides one of the first signals from the transmission unit to each one of individual antennas of the antenna unit. Each antenna transmits one of the first signals and simultaneously receives one of second signals. Each one of a plurality of circulators provides one of a plurality of third signals to the power reduction unit. Each of the third signals comprises one of the second signals and interference generated from the first signals by the antenna unit and the circulator unit. Each one of a plurality of power reducers reduces the power of one of the third signals by multiplying the one of the third signals with a signal splitting factor.
