    • Compressed sensing on ambiguity function domain for high resolution detection 

      Güldoǧan, Mehmet B.; Pilancı, Mert; Arıkan, Orhan (IEEE, 2010)
      In this paper, by using compressed sensing techniques, a new approach to achieve robust high resolution detection in sparse multipath channels is presented. Currently used sparse reconstruction techniques are not immediately ...

    • Compressive sampling and adaptive multipath estimation 

      Pilancı, Mert; Arıkan, Orhan (IEEE, 2010)
      In many signal processing problems such as channel estimation and equalization, the problem reduces to a linear system of equations. In this proceeding we formulate and investigate linear equations systems with sparse ...

    • Recovery of sparse perturbations in Least Squares problems 

      Pilanci, M.; Arıkan, Orhan (IEEE, 2011)
      We show that the exact recovery of sparse perturbations on the coefficient matrix in overdetermined Least Squares problems is possible for a large class of perturbation structures. The well established theory of Compressed ...
