Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, ...

Radio frequency interference (RFI) caused by human communication techniques (e.g., satellites, base stations, and navigation radars) can significantly distort shapes of multichannel time-frequency ...

Radio frequency interference (RFI) arises when man-made or natural radio emissions intrude upon the faint celestial signals sought by radio telescopes. As radio astronomy advances towards greater ...
