... band at 60 GHz to this kind of applications [1]. Communications at 60 GHz have some advantages as well as some disadvantages. The main advantages are three- fold. The large unlicensed bandwidth around ... FE nonidealities: ADC clip- ping and quantization, PN and nonlinearity of the PA. The rationale for choosing these 3 nonidealities is that a good PA, a high resol...

... this case, an iden- tification rate of 0.99 corresponds to a standard deviation in identification rate of 0.005. Thus, the two multiple-band methods have a statistically significant advantage over ... computational cost of the process. An alternative is to subsample each band of the hyperspectral image before concatenation into the large composite image. For example, Figure 8 shows...
