Spectrum decision is the ability of a cognitive radio (CR) to select the best available
spectrum band to satisfy secondary users'(SUs') quality of service (QoS) requirements …

This paper is a survey of the transmission techniques used in digital television (TV)
standards worldwide. With the increase in the demand for High-Definition (HD) TV, video-on …

This paper presents a systematic approach to exploiting TV white space (TVWS) for device-
to-device (D2D) communications with the aid of the existing cellular infrastructure. The goal …

An alternative scheme, named frequency spreading filter bank multicarrier (FS-FBMC), is
introduced for multicarrier transmission. It is based on the FFT and closely follows the …

The electromagnetic spectrum plays a fundamental role in the development of the digital
society. It enables wireless communications (either between humans or machines) and …

In this study, we integrate overlay cognitive radio technology into 4G cellular networks for the
sharing of TV spectrum. On one hand, OFDM is a promising technique for high-speed data …

The increasing number of Internet of Things (IoT) objects has been a growing challenge of
the current spectrum supply. To handle this issue, the IoT devices should have cognitive …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

This paper provides an overview of cognitive radio technology and its applications in the
field of civil aviation. Cognitive radio technology is a relatively new and emerging field that …

Received Signal Strength (RSS) maps provide fundamental information for mobile users,
aiding the development of conflict graph and improving communication quality to cope with …
