    • A Hybrid Energy Sharing Framework for Green Cellular Networks 

      Farooq, Muhammad Junaid; Ghazzai, Hakim; Kadri, Abdullah; ElSawy, Hesham; Alouini, Mohamed-Slim ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      Cellular operators are increasingly turning toward renewable energy (RE) as an alternative to using traditional electricity in order to reduce operational expenditure and carbon footprint. Due to the randomness in both RE ...

    • Antenna subset selection at multi-antenna relay with adaptive modulation 

      Choi, Seyeong; Hasna, Mazen O.; Yang, Hong-Chuan; Alouini, Mohamed-Slim ( John Wiley & Sons, Ltd. , 2013 , Article)
      In this paper, we proposed several antenna selection schemes for cooperative diversity systems with adaptive transmission. The proposed schemes were based on dual-hop relaying where a relay with multiple-antenna capabilities ...

    • Channel modelling and performance analysis of V2I communication systems in blind bend scattering environments 

      Chelli, Ali; Hamdi, Rami; Alouini, Mohamed-Slim ( EMW Publishing , 2014 , Article)
      In this paper, we derive a new geometrical blind bend scattering model for vehicle-to- infrastructure (V2I) communications. The proposed model takes into account single-bounce and double- bounce scattering stemming from ...

    • Effects of Post and Early Selection on SEC Based Transmit Diversity Systems with Linear Power Loading 

      Hasna, M.O.; Yang, Hong-Chuan; Alouini, Mohamed-Slim ( IEEE , 2008 , Conference Paper)
      Switch and examine combing (SEC) diversity scheme provides a lowest-complexity closed-loop transmit diversity solution. Furthermore, by probing sequentially available branches with different power loading levels, the SEC ...

    • Energy management optimization for cellular networks under renewable energy generation uncertainty 

      Ben Rached, Nadhir; Ghazzai, Hakim; Kadri, Abdullah; Alouini, Mohamed-Slim ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      The integration of renewable energy (RE) as an alternative power source for cellular networks has been deeply investigated in the literature. However, RE generation is often assumed to be deterministic; an impractical ...

    • Precoder Design and Power Allocation for MIMO Cognitive Radio Two-Way Relaying Systems 

      Sboui, Lokman; Ghazzai, Hakim; Rezki, Zouheir; Alouini, Mohamed-Slim ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      In this paper, we study a multiple-antenna two-way relaying (TWR) cognitive radio (CR) system. A space alignment (SA) technique is adopted by the secondary users (SUs) to avoid interference with the primary users (PUs). ...

    • Relay selection in underlay cognitive networks with fixed transmission power nodes 

      Hussain, Syed Imtiaz; Abdallah, Mohamed M.; Alouini, Mohamed-Slim; Qaraqe, Khalid; Hasna, Mazen ( John Wiley & Sons, Ltd. , 2013 , Article)
      Underlay cognitive networks operate simultaneously with primary networks satisfying stringent interference constraints, which reduces their transmission power and coverage area. To reach remote destinations, secondary ...
