Hierarchical modulation
WebA simple method, based on elementary fourth-order cumulants, is proposed for the classification of digital modulation schemes. These statistics are natural in this setting as they characterize the shape of the distribution of the noisy baseband I and Q samples. It is shown that cumulant-based classification is particularly effective when used in a … WebElectronic modulation is of great significance for electrocatalysts, as it can intrinsically improve their catalytic properties. Here we realize the electronic strong metal–support interaction (ESMSI) and the electron injection effect on Mo sites by introducing carbon nanotube (CNT) supports and Ni-doping. C
