Abstract: A communication system for the next generation wireless communications technology standards. The communication system architecture is created by the combination of the index modulation technique and the multiple input, multiple output orthogonal frequency division multiplexing which eliminates the need to utilize complex equalizers by parsing high speed data strings and transmitting them over multiple orthogonal subcarriers, and allows the bits to be transmitted via active subcarrier indices. The OFDM-IM and multiple input multiple output communication techniques are used in tandem. The communication system can be used in future generation mobile communication systems and standards (5G and beyond), Local Area Network system and standards, terrestrial digital TV system and standards, multi-carrier communication systems and broadband digital communication systems.

Abstract: A process for producing porous nanostructures suitable for the manufacture of nanowires and processes for manufacturing of the nanowires by using said nanostructure are disclosed. The process for obtaining the nanostructure of the invention comprises the steps of cleaning and polishing the surface of an aluminum metal substrate, forming a porous oxide layer bearing nanoholes on said aluminum substrate, immersing the porous structure into a basic zincate solution for etching the bottoms and walls of the nanoholes and depositing a thin and substantially pure Zn film extending from the bottom of the nanoholes through the aluminum substrate. Nanowires can be fabricated by the step of utilizing so obtained etched nanostructure as an electrode and subjecting the same to a metal electro-deposition operation.
