Family of Nyquist-I Pulses to Enhance Orthogonal Frequency Division Multiplexing System Performance
(Taylor and Francis, 2016)
A family of Nyquist-I pulses called sinc parametric linear combination pulse (SPLCP) is proposed. It is characterized by two novel design parameters that provide additional degrees of freedom to minimize the intercarrier ...
Performance enhancement in OFDM systems with ICI utilizing the improved double jump linear combination pulse
(IEE, 2017)
It is well-know that carrier frequency offset in the subcarriers of orthogonal frequency division multiplexing (OFDM) leads to intercarrier interference (ICI); therefore, system degradation occurs. Nevertheless, this issue ...
Suppressing the effect of ICI power using dual sinc pulses in OFDM-based systems
(Elsevier, 2016)
Sensitivity to frequency offset in orthogonal frequency division multiplexing (OFDM)-based systems allow unwanted interference among the subcarriers, which results in intercarrier interference (ICI). A novel family of ...
Edge-preserving frequency-offset denoising of seismic data
(Society of Exploration Geophysicists, 2018-09)
We have developed new algorithms for denoising 2D or 3D poststack seismic-amplitude data that use simple edge-preserving smoothing operators in the frequency-offset domain. The algorithms are aimed to attenuate random and ...
Estimation Aveugle Itérative par Filtrage H∞ des Décalages Doppler d’un Système OFDMA Entrelacé en Liaison Montante
(2009-07-01)
Il s'agit d'estimer et de compenser de multiples décalages Doppler dans un contexte multi-(porteuses, utilisateurs) OFDMA en liaison montante. Pour cela, nous proposons une architecture de réception itérative capable ...
Improved Nyquist-I Pulses to Enhance the Performance of OFDM-Based Systems
(Springer, 2017)
Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
