Electromagnetic spectrum umbrella cover radio frequency domain self-interference suppression method and system

Abstract

The invention discloses an electromagnetic spectrum umbrella cover radio frequency domain self-interference suppression method and system. The method comprises: a first signal conversion module converting a signal entering through a first input end of a communication receiver and sending the converted signal to an interference signal reconstruction module; the interference signal reconstruction module compensating the local reconstruction interference signal from four dimensions of frequency, time, amplitude and phase, and performing power divider compensation and combiner compensation on thecompensated reconstruction interference signal according to the influence; and the second signal conversion module inputting the compensated signal to the second input end of the combiner through theoutput end of the communication receiver and the amplifier. The invention provides an effective processing architecture for the received radio frequency signal, and the self-interference radio frequency signal can be suppressed within the dynamic range of a receiving channel, so that the saturation of the receiving channel is prevented. The self-interference suppression of the umbrella cover is not limited by the type of a communication signal, the system can be combined with any existing communication link, and is high in compatibility.

Description

technical field [0001] The invention relates to an electromagnetic spectrum umbrella cover system, in particular to a method and system for suppressing self-interference in a radio frequency domain of an electromagnetic spectrum umbrella cover. Background technique [0002] In the past two decades, the contradiction between the explosive growth of wireless communication services and the increasingly scarce electromagnetic spectrum has driven the transformation of wireless communication theory and technology. When the high-power electronic system of the electromagnetic spectrum umbrella is turned on, the radiation power of the simultaneous interference signal of the same frequency far exceeds the sensitivity of the radio receiver of one's own radio station. In serious cases, it directly blocks the front end of the receiver equipment, causing the reception of these equipment to be interrupted. [0003] At present, the self-interference suppression technology given by the acade...
