In this paper we present a thorough study of spectrum sensing performance in cognitive
radio (CR) scenarios where the primary user (PU) transmission is not continuous. In …

Spectrum sensing mechanisms enable cognitive radio networks to detect primary users
(Upsi) and utilize spectrum holes for secondary user (SU) transmission. However, precise …

Various metrics related to the protection of primary user in cognitive radio networks, such as
the detection probability and collision ratio, have been considered in recent years. In this …

Future wireless communications systems are expected to be extremely dynamic, smart and
capable to interact with the surrounding radio environment. To implement such advanced …

Abstract Orthogonal Frequency Division Multiplexing (OFDM) is the popular multicarrier
modulation technique used in wireless communications, especially on fading channel …

Traditionally, maritime business is associated to transportation, which represents about 90%
of global trade, and fishery, but new activities at sea, opened up by technological …
