摘　要:本文分析了在限幅噪声和高斯噪声环境下,在HFC 网中混合传输AM/ OFDM信号时的误 码特性,并与单载波AM/ QAM系统进行比较,结果表明OFDM系统由于多个子通道的稀释作用,其 抗限幅噪声性能比单载波系统好。 关键词:正交频分复用 HFC 网 限幅噪声 误码率-Abstract :Theoretical analysis is presented for the BER performance of hybrid AM/ OFDM system in the pres2

This function can be used for adding different kind of impulse noises (i.e. Salt & Pepper noise and Random-value impulse noise) to image. Salt & Pepper Noise values are 0 or 255 but random-value impulse noise values vary from 0 to 255
