Cover Story: The abundance of radio signals and their increasing number creates interferences on adjacent signals and, sometimes, with co-channel communication. This paper will discuss the effect of continuous wave interference, generally emitted by hackers or military forces, on a radio communication receiver, specifically with the digital video broadcasting for satellite second generation (DVB-S2) communication standard. It investigates the general effect of the interference on a quadrature phase-shift keying signal over each part of the DVB-S2 receiver. It also focuses on the impact of the center frequency and power of the interference on the critical blocks of a DVB-S2 receiver. View this paper
