We present a graphene-based wideband microphone and a related ultrasonic radio that can
be used for wireless communication. It is shown that graphene-based acoustic transmitters …

Summary Underwater Wireless Communication is a rapidly growing technology in the
research domain. The researchers have been working towards the developments in …

In conventional approach, the bit error probability (BEP) expressions of-ary phase-shift
keying (MPSK) signals over additive white Gaussian noise (AWGN) channel are derived by …

Una breve noticia aparecida en la edición del 19 de setiembre de 1990 de un periódico de
tirada nacional informaba de la firma de un acuerdo para la creación de una joint venture en …

Quantum communication aims to provide absolutely secure transmission of secret
information. State-of-the-art methods encode symbols into single photons or coherent light …

Optical signals are subject to a distance-dependent loss as they propagate through
transmission media. High-intensity, classical, optical signals can routinely be amplified to …

We propose an ambient noise reduction technique for underwater acoustic communication
systems in warm shallow water, where the snapping shrimp impulsive noise is a common …

This thesis proposes to marry two separate technologies together. The first technology is that
of visible light communications (VLC), and the second is small molecule and polymer …

This work deals with digital signal processing. Different methods of processing of signals in
an underwater environment are considered. The threshold methods of sonar pseudo-noise …

The concept of cognitive radio (CR) rings a big paradigm shift to the wireless communication
domain. Extending this concept in to wireless mesh networks (WMN) results a CRWMN …
