Abstract
A full duplex radio unit comprising a transmission unit, an antenna, a reception unit, a circulator and a power reduction unit is provided. The transmission unit is adapted to generate a first signal. The circulator is adapted to provide the first signal from the transmission unit to the antenna. The antenna is adapted to transmit the first signal and simultaneously receive a second signal using an identical frequency or frequency band. The circulator is adapted to provide a third signal to the power reduction unit, wherein the third signal comprises the second signal and interference generated from the first signal by the antenna and the circulator. The power reduction unit is adapted to reduce the power of the third signal by multiplying the third signal by factor of √ρ, wherein ρ is between zero and one, thereby generating a fourth signal.
