    • Robust minimax estimation applied to kalman filtering 

      Aybar, Bahadır (Bilkent University, 2008)
      Kalman filtering is one of the most essential tools in estimating an unknown state of a dynamic system from measured data, where the measurements and the previous states have a known relation with the present state. It ...
    • Shallow buried object detection using GPR 

      Kamacı, Nejat (Bilkent University, 1999)
      Ground Penetrating Radar received considerable attention in the use of shallow buried object detection. Differing from the traditional sensor systems such as electro magnetic induction based metal detector sensor, GPR can ...
    • Terrain profile estimation over a synthetic terrain by using pulse-doppler radar 

      Tan, Onur (Bilkent University, 2010)
      The systems used for terrain profile estimation arise when the safety flight issues in civil flight transport and in military applications become important. These systems are developed for the purpose of terrain avoidance ...
    • Time-frequency component analyzer 

      Özdemir, Ahmet Kemal (Bilkent University, 2003)
      In this thesis, a new algorithm, time–frequency component analyzer (TFCA), is proposed to analyze composite signals, whose components have compact time–frequency supports. Examples of this type of signals include biological, ...
    • Uncertain linear equations 

      Pilancı, Mert (Bilkent University, 2010)
      In this thesis, new theoretical and practical results on linear equations with various types of uncertainties and their applications are presented. In the first part, the case in which there are more equations than unknowns ...
    • Wide-band maximum likelihood direction finding by using the tree-structured EM algorithm 

      Çadallı, Nail (Bilkent University, 1996)
      A thorough derivation of the Expectation Maximization (EM) algorithm, which is an iterative numerical method of Maximum Likelihood (ML) estimation, is presented for the case of estimating direction of arrivals of unknown ...
    • Zone based GLRT for detecting physical random access channel signals in 5G 

      Tütüncüoğlu, Feridun (Bilkent University, 2020-01)
      In LTE/5G systems, the random access channel (RACH) process occurs during the boot-up phase. As channel state information is not available at this stage, detecting several devices with high performance presents a challenging ...
