Abstract Most wireless devices transmit and receive at different spectrum frequency bands. Thisapproach is no longer optimal due to increasing electromagnetic exhaustion. Besides, interferenceamong all present and future working services should be negligible. A full-duplex scheme usingthe same band for simultaneous uplink and downlink is a huge step towards solving this issue.However, sharing the same frequency band involves a large interference of transmitted signal overreceived signal. To fix this problem, we propose the usage of a hybrid multistage cancellation system,consisting of an analog cancellation setup at RF frequencies and a baseband digital cancellation stage.
