中文摘要

This paper aims to utilize a self-tuning synthesis filter capable of mutual coupling compensation and interference mitigation. The spatial filter and temporal filter are to compensate for the effect of mutual coupling and interference mitigation, respectively. Self-tuning mechanism is to adopt least square (LS) and minimum variable distortionless response (MVDR) based methods to adjust spatial and temporal weights of antenna array. The experiment platform is established by the embedded
development board. Simulation and experiment results demonstrate that the proposed method can effectively compensate for mutual coupling, mitigate the co-channel interference up to 30 dB and enhance the acquisition performance of global navigation satellite system (GNSS) receivers.
