Channel shortening equalizer based on SVD decomposition in UWB systems

Noureddine Benamara Benotmane, Sid Ahmed Elahmar, Iyad Dayoub

In this paper, we present a novel channel shortening equalizer (CSE) based on the adaptation of energy optimization method on CSE using singular value decomposition (SVD) algorithm in UWB channel with time hopping (TH) and pulse position modulation (PPM). The validity of proposed method as applied...

Time-domain LMMSE channel estimator based on sliding window for OFDM systems in high-mobility situations

Ali Kalakech, Marion Berbineau, Iyad Dayoub, Eric Pierre Simon

Recently, wideband orthogonal frequency-division multiplexing (OFDM)-based systems such as Long-Term Evolution (LTE) have been proposed for future railway communication systems. In such high-speed situations, Doppler phenomena, related to the terminal's high speed, affects the use of OFDM...

Analytic Modeling of the Coexistence of IEEE 802.15.4 and IEEE 802.11 in Saturation Conditions

Eugene David Ngangue Ndih, Soumaya Cherkaoui, Iyad Dayoub

With the increasing deployment of smart wireless devices using different technologies such as IEEE 802.15.4 and IEEE 802.11 which operate in the same frequency band, it becomes urgent to deeply understand the impact of this coexistence on the performance of the involved networks. We present in this...

Comparison of superimposed pilot schemes in iterative receivers for OFDM systems

Farah Zaarour, Eric Pierre Simon, Marie Zwingelstein, Iyad Dayoub

Pilot-aided techniques are classically used to accomplish channel estimation in orthogonal frequency division multiplexing (OFDM) systems. However, those pilots occupy an important bandwidth which could have been allocated to data instead. Superimposed pilots have been proposed as substitutes to...

Performance analysis of multiple-input multiple-output relay networks based impulse radio ultra-wideband

Yamen Issa, Iyad Dayoub, Walaa Hamouda

In this paper, we study the performance of time hopping pulse position modulation for impulse radio ultra-wideband. We consider relay network applying decode-and-forward protocol. The channels between nodes adopt the IEEE 802.15.4a norms. The bit error rate performance is analyzed considering the...

Iterative time domain estimation of rapidly changing channel for OFDM systems in a cognitive radio context

Ali Kalakech, Rony Darazi, Marion Berbineau, Eric Pierre Simon, Iyad Dayoub

Rapidly changing channels typically occurs in high speed situations where Doppler phenomena, related to the terminal's high speed, affects the use of OFDM systems by producing a loss of orthogonality between different carriers. Thus, the channel estimation and equalisation become a challenging...

A low complexity turbo receiver for data nulling superimposed pilots in OFDM

Farah Zaarour, Eric Pierre Simon, Marie Zwingelstein, Iyad Dayoub

The main drawback of classical superimposed pilot (CSP) schemes is the deteriorated channel estimation performance due to interference from data. A recent proposal of a data nulling superimposed pilot (DNSP) scheme in orthogonal frequency division multiplexing (OFDM) was able to circumvent this...

Adaptive Joint Semi-blind Estimation of CFO and Channel for OFDM Systems

Mokhtar Besseghier, Ahmed Bouzidi Djebbar, Iyad Dayoub

The large number of subcarriers, used in OFDM systems, increases the sensivity to frequency offset which results from a Doppler shift, due to mobile movement, as well as from a mismatch between the carrier frequencies at the transmitter and receiver. The problem of channel estimation in a practical...
