As a result of the huge demand and enormous usage of radio frequency spectrum and its
limited resources, the concept of cognitive radio plays a significant role in the efficient usage …

The V2V (Vehicle to Vehicle) communication system in the Internet of vehicular networking
is an important part of the future intelligent vehicle network, and it is extremely important to …

In this paper, we demonstrate a high security subcarrier shifting chaotic orthogonal
frequency domain multiplex (OFDM) cognitive radio (CR) system using universal software …

Progressively, number of radio spectrum users is increasing as life tends towards new
technologies in all sectors, so even those users of licensed band are demanding larger …

The unprecedented growth of massive satellite constellations, as well as the advent of a
significant number of steerable beams and digital payloads, poses new challenges in …

Connectivity with large coverage area; and an increase in spectral efficiency of
communications are highly desired features for any wireless network. The presented …

It is always been desirable to operate radios in full-duplex (FDX) mode to harness the
maximum spectral efficiency despite the challenges it puts forth. Before validating any FDX …

With increasing number of mobile users, there is a huge demand for the radio frequency
spectrum, but it is fixed allocated policy which leads to the springiness of the spectrum [1] …
