    • Computer aided frequency planning for the radio and TV broadcasts 

      Altıntaş, A.; Ocalı, O.; Topçu, S.; Tanyer, S. G.; Köymen, H. (Institute of Electrical and Electronics Engineers, 1996-06)
      The frequency planning of the VHF and UHF broadcasts in Turkey is described. This planning is done with the aid of computer databases and digital terrain map. The frequency offset is applied whenever applicable to increase ...
    • Durağan olmayan çok bileşenli boğucu sinyaller için yeni bir uyarlanir karişma çikarici analizi 

      Durak L.; Arikan, O.; Song V.I. (2005)
      A novel adaptive short-time Fourier transform (STFT) implementation for the analysis of non-stationary multi-component jammer signals is introduced. The proposed time-frequency distribution is the fusion of optimum STFTs ...
    • MPLS automatic bandwidth allocation via adaptive hysteresis 

      Akar, N.; Toksöz, M. A. (Elsevier, 2010-11-29)
      MPLS automatic bandwidth allocation (or provisioning) refers to the process of dynamically updating the bandwidth allocation of a label switched path on the basis of actual aggregate traffic demand on this path. Since ...
    • Optimal streaming under rate constraints (İngilizce) 

      Gurses, E.; Akar G.B.; Akar, N. (2006)
      In this paper, we propose an optimal video streaming framework using retransmissions based on the theory of Markov Decision Processes (MDP). Using MDPs, we calculate average reward optimal policies so as to maximize the ...
    • Performance limits on ranging with cognitive radio 

      Dardari, D.; Karisan, Y.; Gezici, S.; D'Amico, A.A.; Mengali, U. (2009)
      Cognitive radio is a promising paradigm for efficient utilization of the radio spectrum due to its capability to sense environmental conditions and adapt its communication and localization features. In this paper, the ...
    • A scheme for handling connectionless services in connection-oriented networks 

      Abdelati, M.; Arikan, E. (The Institute of Electronics, Information and Communication Engineers, 1997-10-25)
      In this work we propose a pricing scheme which serves as an instrument for managing connectionless services in connection-oriented communication networks. The scheme is able to allocate network bandwidth in a Pareto-optimal ...
    • Theoretical limits on time delay estimation for ultra-wideband cognitive radios 

      Gezici, S.; Celebi H.; Arslan H.; Poor H.V. (2008)
      In this paper, theoretical limits on time delay estimation are studied for ultra-wideband (UWB) cognitive radio systems. For a generic UWB spectrum with dispersed bands, the Cramer-Rao lower bound (CRLB) is derived for ...
