    • A Performance comparision of polar codes with convolutional turbo codes 

      Özgür, Üstün (Bilkent University, 2009)
      Polar codes introduced recently by Arıkan are the first low-complexity codes achieving symmetric capacity for arbitrary binary-input discrete memoryless channels (B-DMCs). Although being theoretically significant, their ...
    • Performance of static and adpative subchannel allocation schemes for fractional frequency reuse in WiMAX networks 

      Kar, Görkem (Bilkent University, 2011)
      We study the downlink performance of WiMAX under fractional frequency reuse (FFR) model. Conventional cellular planning methods can be used for broadband wireless access systems that operate in point-to-multipoint (PMP) ...
    • A survey on scheduling in IEEE 802.16 mesh mode 

      Kas, M.; Yargicoglu, B.; Korpeoglu, I.; Karasan, E. (Institute of Electrical and Electronics Engineers, 2010)
      IEEE 802.16 standard (also known as WiMAX) defines the wireless broadband network technology which aims to solve the so called last mile problem via providing high bandwidth Internet even to the rural areas for which the ...
    • A system level simulation study of WiMAX 

      Başçiftçi, Yüksel Ozan (Bilkent University, 2010)
      In this thesis, we implement a WiMAX system level simulator compliant with the evaluation methodology document published by the IEEE 802.16m Task Group. We study the PHY abstraction of polar codes and integrate polar codes ...
