“…To improve the transmission reliability of an OFDM system with impulse interferences, a great deal of research has been conducted on the mitigation of impulse noise. These research studies can be classified into three categories: nonlinear impulse interference suppression such as pulse blanking, pulse clipping, and joint pulse blanking and pulse clipping [6][7][8][9][10]; interference mitigation based on impulse signal reconstruction such as decisiondirected and compressed sensing [11][12][13][14][15][16]; and impulse mitigation based on coding and iterative decoding [17,18]. Although the transmission reliability of an OFDM system with the nonlinear impulse interference suppression method is inferior to the other two methods, the nonlinear impulse interference suppression method has many advantages such as its low computational complexity, easy engineering implementation, and strong adaptability [19].…”

Nonlinear pulse blanking is a widely applied method to mitigate the impulse interference of orthogonal frequency division multiplexing (OFDM) systems. To quantitatively analyze the capacity of the OFDM system with nonlinear pulse blanking, the analytical expressions of the instantaneous output signal-to-interference-plus-noise ratio of the OFDM system with ideal blanking, peak value blanking, and optimum threshold blanking are first derived. The probability density function of the instantaneous capacity of the OFDM system with nonlinear pulse blanking is then estimated by the finite mixture with the expectation-maximization algorithm. The ergodic capacity and the probability of the outage capacity of the OFDM system with nonlinear pulse blanking are obtained based on the estimated probability density function. Finally, the simulation results are provided to indicate its good agreement with the theoretical results.
