الملخص: front page image
(EN) An embodiment of the invention discloses a signal interference restraining method, device and system which is used for increasing frequency spectrum utilization rate. The method includes: transmitting a transmitting signal through a transmitting antenna; simulating and rebuilding the transmitting signal to obtain a simulated and rebuilt signal; acquiring a self-interference signal and a business signal through a receiving antenna; performing digital rebuilding on the transmitting signal according to the self-interference signal to obtain a digital rebuilt signal; performing power synthesis on the simulated and rebuilt signal and the digital rebuilt signal to obtain a rebuilt signal; using the rebuilt signal to offset the self-interference signal so as to lower the interference of the transmitting signal to the business signal.
(ZH) 本发明实施例公开了一种信号干扰的抑制方法和装置及系统,用于提高频谱利用率。本发明实施例方法包括:通过发射天线将发射信号发射出去;对所述发射信号进行模拟重建,得到模拟重建信号;通过接收天线获取自干扰信号和业务信号;根据所述自干扰信号对所述发射信号进行数字重建,得到数字重建信号;对所述模拟重建信号和所述数字重建信号进行功率合成,得到重建信号;使用所述重建信号对所述自干扰信号进行抵消,以降低所述发射信号对所述业务信号的干扰。
