Although cochlear implants work well for people with hearing impairment in quiet conditions,
it is well-known that they are not as effective in noisy environments. Noise reduction …

For the state-of-the-art speech enhancement (SE) techniques, a spectrogram is usually
preferred than the respective time-domain raw data, since it reveals more compact …

To address the exploding traffic demands for mobile data, non-orthogonal multiple access
(NOMA) schemes for resource allocation are considered as one of the potential candidates …

In this brief, we consider an advanced noise reduction differential chaotic shift keying system
in which a single antenna source communicates with a single antenna destination under the …

In last few years, several recent developments concern a new proposed techniques of
communication for WSN (Wireless Sensors Network) using a complex methods and …

Body networks type WBAN (Wireless Body Area Network) are beginning to take a major
interest in last years. Generally, modern transmission face three major challenges: energy …

Most state-of-the-art speech enhancement (SE) techniques prefer to enhance utterances in
the frequency domain rather than in the time domain. However, the overlap-add (OLA) …

Aujourd'hui, les systèmes de communication numériques revêtent une importance
considérable dans de nombreux domaines et représentent un point de convergence des …

The main objective of this research work is to propose a new method of communication
adapted to sensor networks for both one-to-many and many-to-one topologies. This type of …

One of the goals of astrophysics is to obtain a full understanding how the Universe is
organized on large scales and how structure evolved. In this thesis we develop a method of …
