Radio Workshop Report: Technical Methods and Strategies for Mitigating Radio Frequency Interference (RFI)

Analog Radio-Frequency Interference (RFI) Suppression System for Microwave Radiometers

—Microwave radiometers use radio spectrum dedicated to sensing the environment. As wireless communications and other active services proliferate, this allocated spectrum is nearly being crowded out. The potential result is corrupted satellite measurements of the weather, the climate, and the environment. The Analog Radio-Frequency Interference Suppression System (ARFISS) is a combination of det...

RFI mitigation methods in radio astronomy

Various methods of radio frequency interference (RFI) mitigation methods at radio astronomy telescopes are being considered. Special attention is given to real-time processing algorithms. Computer simulations and observational results are used to describe the applicability of these methods. Best results can be achieved when the RFI mitigation procedures are adapted to the particular radio teles...

Radio Frequency Interference Mitigation in Radio Astronomy

Radio Frequency Interference

We describe the nature of the interference challenges facing radio astronomy in the next decade. These challenges will not be solved by regulation only, negotiation and mitigation will become vital. There is no silver bullet for mitigating against interference. A successful mitigation approach is most likely to be a hierarchical or progressive approach throughout the telescope and signal condit...

Technical Report: Equilibrium Pricing of Interference in Cognitive Radio Networks

Dynamically allocating the available spectrum in the cognitive radio networks (CRN) where licensed users allow unlicensed users to make use of part of their allocated spectrum is a complex task. It requires, among others, that the interference generated by the CRN is well controlled. In this paper we address this problem for a particular type of interference constraints, in which the aggregated...
