| Abstract(in English) | In-band full duplex, which is a new communication system attracting attention for 5G and beyond, can transmit and receive information simultaneously at same frequency band. However, self-interference cancellation is essential for realizing in-band full duplex. In this report, we describe evaluations of digital adaptive filters for self-interference cancellation implemented on a software-defined radio. It is studied to apply digital adaptive filters to both the analog stage and the digital stage to realize self-interference elimination. The authors implement these filters on the Universal Software Radio Peripherals (USRPs). We clarify that the developed system achieves self-interference cancellation of about 30 dB. Also, we consider the influence of the phase noises of local oscillators on the system. |
