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 ...
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 ...
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, ...
Determining F2 layer parameters via optimization using IRI model and IONOLAB TEC estimations
(IEEE, 2011)
We know that F2 layer of the ionosphere is most important layer in the progaration of high frequency (HF) waves. In this study, The relation of the height (HmF2) and the critical frequency (FoF2) of F2 layer-among the ...
Generalized time-bandwidth product optimal short-time fourier transformation
(IEEE, 2002-05)
By extending the time-bandwidth product concept to fractional Fourier domains, a generalized time-bandwidth product (GTBP) is introduced. The GTBP provides a rotation independent measure for the support of the signals in ...
Adaptive filtering approaches for non-Gaussian stable processes
(IEEE, 1995-05)
A large class of physical phenomenon observed in practice exhibit non-Gaussian behavior. In this paper, α-stable distributions, which have heavier tails than Gaussian distribution, are considered to model non-Gaussian ...
Optimization of F2 layer parameters using IRI-Plas model and IONOLAB Total Electron Content
(IEEE, 2011)
In this study, the relation of the maximum ionization height (HmF2) and the critical frequency (FoF2) of F2 layer is examined within their parametric range through the International Reference Ionosphere extended towards ...

Stochastic signaling under second and fourth moment constraints
(IEEE, 2010)
Stochastic signaling is investigated under second and fourth moment constraints for the detection of scalar-valued binary signals in additive noise channels. Sufficient conditions are derived to determine when the use of ...
Recovery of sparse perturbations in Least Squares problems
(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 ...
