本文分析比较了在存在脉冲噪声的情况下，采用消隐、限幅和消隐-限幅组合非线性预处理器的OFDM接收机的性能。推导出了三种类型非线性输出的信噪比的闭合解析表达式。仿真结果与理论吻合较好。
In this paper, we analyze and compare the performance of OFDM receivers with blanking, clipping and combined blanking-clipping nonlinear preprocessors in the presence of impulsive noise. Closed-form analytical expressions for the signal-to-noise ratio at the output of three types of nonlinearity are derived. Simulation results are provided that show good agreement with theory.
