Wireless covert communication is the technology of hiding messages in wireless
communication data frames and signals for covert transmission, which belongs to the cross …

In this paper, we consider the discretely observed hyperbolic diffusion model with two types
of small noises. The least square method is utilized to derive the drift parameter estimator …

Purpose In contrast to traditional communication systems, slower data rate has always
remained a weak link for non-traditional random communication systems (RCSs), which use …

Previously, the concept of Pilot Assisted Synchronization (PAS) and Fractional Lower Order
Covariance (FLOC) has been incorporated together to synchronize alpha-stable noise …

With the gradual popularization of 5G communications, the application of multi-antenna
broadcasting technology has become widespread. Therefore, this study aims to investigate …

In this paper, an electromagnetic nano random communication system (EM-nRCS) has been
proposed which ensures covert communication in the terahertz (THz) band. In the proposed …

In this study, a covert communication method called as random pulse width modulation
(RPWM) is proposed for secure communication where the signals are obtained from the …

In the proposed random communication system (RCS), the alpha‐stable (α‐stable) noise as
a random carrier drives the transmitter which is modelled by the linear dynamical system …

Invisibility of alpha‐stable (α‐stable) noise as carrier signals, in the presence of additive
white Gaussian noise (AWGN) as channel noise, is a key factor to ensure covert …
