The noise term is often constructed by passing the BK/G noise through a band-limiting filter [9]. The bandwidth of this filter is set to 3 kHz for HF channel[37]. This filter is used in practice to minimize the transmission bandwidth. The SNR at the output of band-limiting filter...
AsFig. 13.4shows, the second filter is an EMI filter. Notably, in industry this filter is commonly referred to as radio frequency interference (RFI) filter. The role of this filter is to damp the generated high-frequency noise emissions. Currently, it mainly targets EMI noises of above 150...
But this design was for a source of pink noise only, the pink noise filter ensuring a near-Gaussian distribution. Actually, two filters were used, providing two output channels. These could either be from the same sequence of 0 s and 1 s in the same phase (‘mono’ mode), or one ...
