The spectrum sensing scheme suffers from a physical layer attack of Primary User Emulation
Attack (PUEA). The resolution is to mitigate the cognitive radio user from the PUEA under the …

IoT network-connected devices are increasing day by day. It is impossible to allocate a
spectrum for all IoT devices. This spectrum scarcity can be solved by cognitive radio-based …

In wireless communication, Full-Duplex (FD) is considered as a crucial method for boosting
spectral efficiency. An inexpensive passive reflecting array called Intelligent Reflecting …

In the Internet of Things (IoT) scenario, many devices will communicate in the presence of
the cellular network; the chances of availability of spectrum will be very scary given the …

A good wireless device in a system needs high spectral efficiency. Non-Orthogonal Multiple
Access (NOMA) is a technique used to enhance spectral efficiency, thereby allowing users …

Vacant frequency bands are used in cognitive radio (CR) by incorporating the spectrum
sensing (SS) technique. Spectrum sharing plays a central role in ensuring the effectiveness …

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 …

This paper presents the design of a reliable spectrum sensing method using fuzzy logic and
genetic algorithm. Fuzzy logic acts as a decision-making system. It is used to select an …

Cell-Free massive MIMO (mMIMO) offers promising features such as higher spectral
