This paper presents a mathematical analysis of the joint effects of additive white Gaussian noise and gated noise in an M-ary Quadrature Amplitude Modulation communication system subject to Nakagami fading. This channel model is suitable to describe scenarios in which the Nakagami channel is affected by noisy signals originated from switching electronic circuits present in industrial environments, for example. Novel and exact analytic expressions for the bit error probability of the system are derived and computer simulations corroborate the analytic results.
