Improved Eigenfilter Design Method for Channel Shortening Equalizer in TH-UWB

Noureddine Benamara Benotmane, Sid Ahmed Elahmar, Iyad Dayoub, Walaa Hamouda

The large delay spread of ultra-wideband (UWB) channels causes intersymbol interference and therefore increases the complexity of a UWB Rake receiver. To resolve these problems, we present a new method for the design of channel shortening equalizers (CSE) in time-hopping UWB systems. Our proposed…

Performances of an Optical OFDM-DMT System over Multimode Optical Fiber

Mahdi Kasmi, Sofien Mhatli, Faouzi Bahloul, Iyad Dayoub

In this paper, we present the orthogonal frequency division multiplexing (OFDM) technique based on discrete multitone modulation (DMT) over multimode fiber (MMF), at length up to 5Km at a bit rate of 20 Gb/s. Through numerical simulations, we investigate the optimal launching conditions of the MMF…

Blind Spectrum Sensing Using Extreme Eigenvalues for Cognitive Radio Networks

Iyad Dayoub, Kais Bouallegue, M Gharbi, Kais Hassan

Here, a new spectrum sensing method, called mean-to-square extreme eigenvalue (MSEE), is proposed. Considering a multiple antenna communication system, the proposal is drawn from the arithmetic-to-geometric mean (AGM) algorithm using only the smallest and the largest eigenvalues of the covariance…

On Doubly selective Channel Estimation for FBMC-OQAM using the LMMSE Filter for Future Railway Communications

Michel Saideh, Marion Berbineau, Iyad Dayoub

Filter Bank Multi Carrier (FBMC) based waveforms received recently a lot of interest due to their high frequency localization and hence their suitability to the fragmented spectrum utilization. In this paper, we analyze the doubly selective channel estimation aspect of the FBMC-OQAM waveform. We…

Performance evaluation of an IMDD optical OFDM-CDMA system

Sofien Mhatli, Hichem Mrabet, Elias Giacoumidis, Iyad Dayoub

In this paper, we propose a modulation technique for passive optical networks that harnesses two-dimensional prime hop system optical code division multiplexing access (OCDMA) and optical orthogonal frequency-division multiplexing (OFDM) for intensity modulation with direct-detection (IMDD) to…

MIMO relaying networks for cooperative spectrum sensing: False alarm and detection probabilities

Imen Souid, Haithem Ben Chikha, Iyad Dayoub, Rabah Attia

In this paper, we investigate spectrum sensing in cooperative networks. Hence, in order to enhance cooperative sensing, we propose a novel model based on multiple-input multiple-output (MIMO) relaying broadcast channels with direct link and cognitive radio technology. Despite their efficiency in…

A low complexity joint semi-blind estimation of CFO and channel for OFDM systems

Masmoudi Ramadhan, Ahmed Bouzidi Djebbar, Iyad Dayoub

It is well known that the maximum likelihood (ML) algorithm is characterized by their complexity, which is very high. This paper presents a low-complexity semi-blind algorithm to jointly estimating the Carrier Frequency Offset (CFO) and channel based on oversampling in the receiving part for an…

Spectrum sensing for wireless communications using energy ratio and beamforming

Kais Bouallegue, Iyad Dayoub, M Gharbi

In this paper, a new spectrum sensing (SS) method, called maximum-to-mean energy detector (MMED), is proposed. Considering a wireless communication system with many angles of arrival (AoA), the suggested method is based on beamforming and the ratio of the maximum energy to the mean one of the…
