    • Optimized Selective OFDMA in multihop network 

      Gouissem A.; Hasna , Mazen; Hamila R.; Besbes H.; Abdelkefi F. ( IEEE , 2012 , Conference Paper)
      Selective OFDMA is a powerfull relaying technique with subcarrier based selection. This scheeme has a high potential to considerably improve the performance of cooperative OFDM systems. However, in practice, the implementation ...

    • Outage performance of OFDM Ad-hoc routing with and without subcarrier grouping in multihop network 

      Gouissem A.; Hasna , Mazen; Hamila R.; Besbes H.; Abdelkefi F. ( IEEE , 2012 , Conference Paper)
      In this contribution, we investigate Decode and Forward (DF) OFDM Ad-hoc Routing strategy with bottleneck maximization. We derive the exact outage probability and diversity order for the different scenarios: with and without ...

    • Robust GNC approach for quantised compressed sensing 

      Elleuch, I.; Abdelkefi, F.; Siala, M.; Hamila, R.; Al-Dahir, N. ( Institution of Engineering and Technology , 2017 , Article)
      Practical acquisition of compressed sensing measurements involves a finite-range finite-precision quantisation step. To solve the sparse recovery problem and handle the quantisation distortion, this Letter proposes a ...
