Abstract :
This paper presents the design of an RF self-interference cancellation circuit for the full duplex wireless communication systems. Excellent performance is achieved. The RF cancellation circuit provides more than 50dB self-interference cancellation across a 50MHz bandwidth. The transmitted power can be quite high for very low IMD products will be introduced in the circuit. The real time optimization algorithm is used to adaptive adjust the parameters of the circuit according to the change of the channel.
