In order to improve the coexistence power utilization efficiency of the 5G system and WLAN multi-communication system and obtain the coexistence power interference control method,a self-interference control circuit is designed based on coexistence power related domain detection.The design process of offset link,detection circuit,automatic reference level control and real-time adjustment algorithm is described.Based on the self-interference control circuit module,the coexistence power interference control scheme based on 5G system and WLAN is proposed to realize the effective control of coexistence power interference.Experimental results indicate that the proposed control method of coexistence power interference suppression meets the design requirement;that is,the suppression degree of transmitted signals is higher than 50 dB when the bandwidth is over 50 MHz.%为了提高5G系统与WLAN多重通信系统的共存电源利用率,研究该系统的共存电源干扰控制方法,设计一种基于共存电源相关域检测的自干扰控制电路.详细描述了电路中的抵消链路、检测电路、自动参考电平控制以及实时调整算法的设计过程,基于自干扰控制电路模块,提出5G系统与WLAN的共存电源干扰控制方案,实现共存电源干扰的有效控制.实验结果说明,所提控制方法对共存电源干扰抑制度满足设计要求,在高于50 MHz带宽时对发射信号的抑制度高于50 dB.
