Analysis of Adaptive Array Algorithm Performance for Satellite Interference Cancellation in Radio Astronomy
In this paper we evaluate suitability of several array processing methods for adaptively canceling interfering signals present in radio astronomy. The issue of signal corruption by orbital satellite downlink signals, such as from GLONASS and IRIDIUM, is addressed. Simulation and real data analysis of the achievable SINR improvement and beam mainlobe distortion for five candidate algorithms is p...
متن کاملAn Experimental Setup to Develop Rfi Mitigation Techniques for Radio Astronomy
Increasing levels of Radio Frequency Interference (RFI) are a problem for research in radio astronomy. Various techniques to suppress RFI and extract astronomical signals from data affected by interference are being tried out. However, extracting weak astronomical signals in the spectral region affected by RFI remains a technological challenge. In this paper, we describe the construction of an ...
متن کاملImproved interference cancellation in synthesis array radio astronomy using auxiliary antennas
This paper discusses how using a few low-gain auxiliary antennas as pan of a radio astronomy (RA) imaging m a y makes it possible to obtain outstanding rejection of interfering sources. We are particularly interested in canceling interference from orbital satellite downlink signals such as from GLONASS and IRIDIUM. These very strong interferers affect critical observation spectral bands used in...
متن کاملCognitive Anti-Jamming Framework with Self-Interference Cancellation on a Wideband Autonomous Cognitive Radio
With crowded usage of the wireless spectrum, full-duplex wireless systems are introduced to increase bandwidth efficiency by transmitting and receiving on the same frequency band at the same time. Full-duplex communication is a promising solution for greater wireless communications efficiency but, it requires solving the problem of self-interference. SelfInterference cancellation is the process...
متن کاملOn The Secrecy of the Cognitive Interference Channel with Channel State
In this paper the secrecy problem in the cognitive state-dependent interference channel is considered. In this scenario we have a primary and a cognitive transmitter-receiver pairs. The cognitive transmitter has the message of the primary sender as side information. In addition, the state of the channel is known at the cognitive encoder. Hence, the cognitive encoder uses this side information t...
