Nowadays, wireless communication has been widely used in our life. As one of the results, the radio frequency spectrum resource becomes less and less. In Band Full-Duplex has a great potential to improve the efficiency of the RF spectrum and is developing by the worldwide research team. In Band Full-Duplex transmits uplink and downlink signal in the same frequency band and at the same time. It can not only improve the spectrum efficiency not also shorter the latency. However, In Band Full-Duplex also create a major problem which is the strength self-interference. The goal of this project is to evaluate the self-interference cancellation techniques. The self-interference cancellation techniques can be applied in three domains, antenna domain, analog domain and digital domain. Self-Interference cancellation in antenna domain mainly uses the particular design in antenna and the property of radio frequency to reduce the self-interference. Since the self-interference is the transmit signal which known, self-interference cancellation in analog and digital use and process the known transmitted signal and used that to cancel the received self-interference. This project used the MATLAB to simulated and evaluated the self-interference cancellation ability in a different situation for various self-interference cancellation techniques.
