Dropout is one of the most widely used methods to avoid overfitting neural networks. However, it rigidly and randomly activates neurons according to a fixed probability, which is not consistent with the activation mode of neurons in the human cerebra

In order to achieve the transmission of more extra information bits, a new design, called spatial modulation with spatial constellation design (SM-SC), is proposed to extend the size of a spatial constellation diagram in spatial modulation (SM) syste

In this letter, we propose a novel scheme extending index dimension with two distinct signal constellations, named as generalized spatial modulation with multi-index modulation (GSM-MIM). Through this scheme, which exploits the spatial domain and ind
