Multiplexing scheme for anti-jamming global navigation satellite system receivers

This study proposes a multiplexing scheme capable of adaptively responding to various forms of interference. The scheme comprises a signal detector, decision logic and interference mitigation modules. Following the detection and characterisation of interference, decision logic is used to select a specific interference mitigation module to effectively nullify or remove that form of interference. This study conducted simulations of continuous wave interference and spoofing signals. The experimental results demonstrate the ability of the proposed scheme to effectively detect and mitigate interference, particularly in the presence of multiple types of interference. Comparisons and analysis of relevant anti-jamming techniques are also presented.
