Jamming destroys the integrity and functionality of the Global Satellite Navigation System (GNSS) in various applications. Hence, anti-jamming techniques are critical. The most significant problem with the existing array-based anti-jamming technique in GNSS is the errors introduced in the carrier phase, which affects the GNSS solution, especially for high-precision measurement applications. We present...
Complex valued blind signal processing is a frequently arising problem in signal processing, and it is an effective method to the resolve linear convolutional mixing problem. In this paper, based on the circularity of the signal, we proposed a new complex valued blind signal extraction method to realize the interference suppression in civil aviation air-to-ground communication. The new method can...
VHF air-to-ground communication is very important for the communications between air traffic controllers and pilots in civil aviation. However, due to various kinds of reasons, radio interference exists in the VHF communication link and has posed a great threat to the civil aviation safety. In this paper, we first establish a practical data model for the problem of interest, then a blind signal extraction...
