Self-Interference Suppression in Radio Frequency Domain for Integrated Communication and Reconnaissance Systems

In order to address the problem that the high-power electromagnetic wave signals emitted by the communication equipment seriously interfere with the reconnaissance equipment on the same multifunctional integrated platform, this paper proposes a multi-tap self-interference suppression method in a radio frequency (RF) domain. To optimize the parameters of the proposed methods, a stochastic approximation algorithm is investigated. Through Matlab simulation, the self-interference suppression performance of the proposed method under different bandwidths, tap numbers, and device resolutions is tested to validate the feasibility of this architecture.
