摘要:

发射机共址带来的强自干扰是实现带内全双工(IBFD)系统的瓶颈。若抑制不足,强干扰会使接收机的模数转换器(ADC)饱和,进而导致数字处理失效。本文考虑利用可重构智能表面(RIS)结合接收(Rx)移相器网络(PSN),通过联合优化二者的相位来抑制强自干扰。该方法名为利用RIS和PSN的自干扰抑制(SIMRP),可有效抑制自干扰以避免ADC饱和,从而提升通信系统的和速率性能,仿真研究验证了这一结论。

英文摘要:

Strong self-interference due to the co-located transmitter is the bottleneck for implementing an in-band full-duplex (IBFD) system. If not adequately mitigated, the strong interference can saturate the receiver's analog-digital converters (ADCs) and hence void the digital processing. This paper considers utilizing a reconfigurable intelligent surface (RIS), together with a receiving (Rx) phase shifter network (PSN), to mitigate the strong self-interference through jointly optimizing their phases. This method, named self-interference mitigation using RIS and PSN (SIMRP), can suppress self-interference to avoid ADC saturation effectively and therefore improve the sum rate performance of communication systems, as verified by the simulation studies.
