    • Differential entropy of the conditional expectation under additive gaussian voise 

      Atalik, Arda; Köse, Alper; Gastpar, Michael (Institute of Electrical and Electronics Engineers, 2022)
      The conditional mean is a fundamental and important quantity whose applications include the theories of estimation and rate-distortion. It is also notoriously difficult to work with. This paper establishes novel bounds on ...
    • The Price of Distributed: Rate Loss in the CEO Problem 

      Atalik, Arda; Köse, A.; Gastpar, M. (Institute of Electrical and Electronics Engineers (IEEE), 2022-04-14)
      In the distributed remote (CEO) source coding problem, many separate encoders observe independently noisy copies of an underlying source. The rate loss is the difference between the rate required in this distributed setting ...
    • Radar antenna selection for direction-of-arrival estimations 

      Atalik, Arda; Yılmaz, Mustafa; Arıkan, Orhan (IEEE, 2021-06-18)
      Multi-antenna radars exhibit positively correlated detection performance with the number of elements utilized. The feasibility of refining antenna arrays to reduce cost of operation with only marginal loss of performance ...
