Spectrum sensing (SS) is an essential task of the secondary user (SU) in a cognitive radio system. SS monitors the primary user (PU) activity in order to avoid any collision with SU, as the latter should be silent when PU is active on a given channel

Cancelation of LNA distortions in in‐band full‐duplex systems

Autor: Hussein Charara, Ali Mansour, Abbass Nasser, Hani Abdallah, Koffi Clément Yao

Publikováno v: Transactions on emerging telecommunications technologies
Transactions on emerging telecommunications technologies, Wiley-Blackwell, 2018, 29 (9), pp.E3426. ⟨10.1002/ett.3426⟩

International audience; In‐band full‐duplex (FD) transceiver has been recently proposed to double the channel efficiency. The main challenge of such FD transceiver consists in achieving an efficient self‐interference cancelation. This fact is p

Human Behavior Modeling in Video Surveillance of Conference Halls

Autor: Nour Charara, Hussein Charara, Omar ABOU KHALED, Hani Abdallah, Elena Mugellini

Publikováno v: BASE-Bielefeld Academic Search Engine

In this paper, we present a human behavior modeling approach in videos scenes. This approach is used to model the normal behaviors in the conference halls. We exploited the Probabilistic Latent Semantic Analysis technique (PLSA), using the 'Bag-of-Te

Evaluation of Scalability and Bandwidth Efficiency of Multipoint to Multipoint Hierarchy for Fast Recovery in MPLS Networks

Autor: Hussein Charara, Mohamad Chaitou

Publikováno v: International journal of Computer Networks & Communications. 6:167-180

Multi-Point to Multi-Point Traffic Engineering (MP2MP-TE) leads to an important scalability in Multi Protocol Label Switching-Traffic Engineering (MPLS-TE) networks. This paper emphasizes on the support of Fast-reroute (FRR) in MPLS-TE networks by us
