    • A concave-convex procedure for TDOA based positioning 

      Gholami, M. R.; Gezici, S.; Strom, E. G. (IEEE, 2013)
      This letter investigates the time-difference-of-arrival based positioning problem in wireless sensor networks. We consider the least-mean absolute, i.e., the ℓ1 norm, minimization of the residual errors and formulate the ...
    • Signal denoising by piecewise continuous polynomial fitting 

      Yıldız, Aykut; Arıkan, Orhan (IEEE, 2010)
      Piecewise smooth signal denoising is cast as a non-linear optimization problem in terms of transition boundaries and a parametric smooth signal family. Optimal transition boundaries for a given number of transitions are ...
