A comparative study of map building techniques by processing sonar arc-maps
(2005)
In this study, four signal processing schemes regarding sonar sensor based map-building applications were compared. The newly proposed method, Directional Maximum is found to be successful in terms of reducing the innate ...
Optimal sampling of multidimensional periodic band-limited signals
(IEEE, 2005)
In this paper, we present an algebraic description of the aliasing phenomena evident in the linear sampling process of multidimensional periodic band limited signals. Opposed to the classical Shannon sampling, periodic ...
Bağlamsal çıkarımla nesne sezimi
(IEEE, 2009-04)
Bu bildiride, sezim başarımını arttırmada tek tek sezilmiş nesneler arasındaki bağlamsal ilişkilerden yararlanan bir nesne sezim sistemi tanıtılmaktadır. Bu çalışmadaki ilk katkı, iki boyutlu görüntü uzayında yapılan ...
Çok kullanıcılı çok antenli sistemlerde iş birlikli iletim
(IEEE, 2008-04)
Bu çalışmada işbirlikli, çok kullanıcılı, ve çok antenli bir haberleşme sisteminde telsiz erişim terminallerinin en iyi veri iletimi tekniğine ortaklaşa karar vermeleri problemini inceliyoruz. Burada pek çok çalışmadan ...
Effects of signal randomization on performance of binary communications systems
(IEEE, 2010)
In this paper, effects of signal randomization are studied for binary communications systems. First, it is stated that the average probability of error for a power-constrained binary communications system is minimized when ...
Average fisher information optimization for quantized measurements using additive independent noise
(IEEE, 2010)
Adding noise to nonlinear systems can enhance their performance. Additive noise benefits are observed also in parameter estimation problems based on quantized observations. In this study, the purpose is to find the optimal ...
A novel objective function minimization for sparse spatial filters
(IEEE, 2014)
Common spatial pattern (CSP) method is widely used in brain machine interface (BMI) applications to extract features from the multichannel neural activity through a set of spatial projections. The CSP method easily overfits ...
Wide-band maximum likelihood direction finding by using tree-structured EM algorithm
(IEEE, 1996)
A tree structured Expectation Maximization (EM) algorithm is proposed and applied to the wide-band angle of arrival estimation. It may be seen as a generalization on EM using the ideas of Cascade EM algorithm and Space ...
Optimal stochastic signal design and detector randomization in the Neyman-Pearson framework
(IEEE, 2012-03)
Power constrained on-off keying communications systems are investigated in the presence of stochastic signaling and detector randomization. The joint optimal design of decision rules, stochastic signals, and detector ...
A survey on optimal stochastic signaling and detector randomization
(IEEE, 2011)
In this paper, a survey on stochastic signaling and detector randomization is presented for average power-constrained binary communications systems. First, the case of a single fixed detector at the receiver is considered, ...
