Over the years extensive studies have been carried out to apply coherent optics methods in
real-time communications and image transmission. This is especially true when a large …

This manuscript presents a survey on new challenges in wireless communication systems
and discusses recent approaches to address some recently raised problems by the wireless …

Acoustic waves carry information about their source and collect information about their
environment as they propagate. This article reviews how these information-carrying and …

This paper considers the problem of blindly separating sub-and super-Gaussian sources
from underdetermined mixtures. The underlying sources are assumed to be composed of …

Singular spectrum analysis (SSA) is a powerful approach to separate sources from the
mixed signal. There is an important factor when SSA is used for extracting each source …

Sound that travels through the ocean from a source to a receiver is commonly distorted by
multipath acoustic propagation. The severity and details of this distortion are determined by …

This paper studies the existing links between two approaches of Independent Component
Analysis (ICA)–FastICA/projection pursuit and Infomax/Maximum likelihood estimation–and …

Spectrum Sensing problem is a major problem in any smart radio transmission system (ie
Cognitive or Smart Radio). This manuscript deals with this problem by proposing two major …

Since the beginning of the last two decades, many researchers have been involved in the
problem of Blind Source Separation (BSS). Whilst hundreds of algorithms have been …

In this paper, we propose a new and simple algorithm for blind separation of sources based
on geometrical concepts. This algorithm deals with the instantaneous mixtures and does not …
