    • Hybrid underlay/overlay cognitive radio system with hierarchical modulation in the presence of channel estimation error 

      Shaker, Reza; Khakzad, Hamidreza; Taherpour, Abbas; Khattab, Tamer; Hasna, Mazen Omar ( IEEE , 2014 , Conference Paper)
      In this paper, we study the performance of hybrid cognitive radio (CR) system in the presence of channel estimation error (CER) in terms of bit-error-probability (BEP) and outage probability. We assume simultaneous switching ...

    • Optimal Group Formation in Dense Wi-Fi Direct Networks for Content Distribution 

      Khan, Muhammad Asif; Hamila, Ridha; Hasna, Mazen Omar ( Institute of Electrical and Electronics Engineers Inc. , 2019 , Article)
      Wi-Fi Direct enables direct communication between Wi-Fi devices by forming Peer to Peer (P2P) groups. In each P2P group, one device becomes the Group Owner (GO) and serves as an access point (AP) to connect the remaining ...

    • Power control and RB allocation for LTE uplink 

      Essassi, Safa; Siala, Mohamed; Hamila, Ridha; Hasna, Mazen Omar; Cherif, Sofiane ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      According to 3GPP standards, the Single Carrier Frequency Division Multiple Access (SC-FDMA) was adopted for Uplink transmission in LTE networks. As multiple mobiles may have access to neighboring base stations simultaneously, ...

    • Power control and RB allocation in cloud radio access networks 

      Essassi, Safa; Hamila, Ridha; Cherif, Sofiane; Siala, Mohamed; Hasna, Mazen Omar ( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)
      In the LTE system the fractional power control and the universal frequency reuse have been targeted. The fractional power control approach decreases the inter-cell interference but may impact the throughput. The universal ...

    • RB allocation based on genetic algorithm in cloud radio access networks 

      Essassi, Safa; Hamila, Ridha; Cherif, Sofiane; Siala, Mohamed; Hasna, Mazen Omar ( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)
      This work proposes a method to optimize the resource block allocation in the cloud radio access network for a long term evolution system. This approach consists in three steps. First, the baseband unit collects the required ...
