Narrowband interference suppression algorithm for sea battlefield integrated synesthesia system
This article constructs an integrated communication and perception system with the ability to perceive target wells and communicate with users,and optimizes the balance between radar detection performance and communication per-formance.In the communication environment of naval battlefields,signals are often affected by narrowband interference dur-ing transmission,causing significant damage to communication quality.In response to this issue,this article designs a nar-rowband interference suppression algorithm that combines with a comprehensive communication perception system.This al-gorithm improves the classic threshold algorithm to achieve threshold adaptation.Finally,the harm of narrowband interfer-ence and the necessity of removing narrowband interference were demonstrated through simulation.The bit error rate of the signal under narrowband interference was compared with the signal processed by this algorithm to prove the effectiveness of the algorithm.The algorithm was compared with traditional algorithms to demonstrate the improvement of algorithm per-formance.
