Intelligent Reflecting Surfaces to Achieve the Full-Duplex Wireless Communication
IEEE Communications Letters, 2020The full-duplex (FD) radio-frequency wireless communication theoretically doubles the data rates compared to the half-duplex counterpart. However, its performance depends critically on the self-interference (SI) that exists between transmit and receive ...

MISO Wireless Communication Systems via Intelligent Reflecting Surfaces : (Invited Paper)
2019 IEEE/CIC International Conference on Communications in China (ICCC), 2019Intelligent reflecting surfaces (IRSs) have received considerable attention from the wireless communications research community recently. In particular, as low-cost passive devices, IRSs enable the control of the wireless propagation environment, which ...
