In this article, a non-linear adaptive beamforming technique, Adaptive Projections Subgradient Method (APSM) [1] is considered. This technique uses projections over convex sets in Reproducing Kernel Hilbert Space. Main advantage of this technique is observed if the signal-of-interest is due to digital modulation and when there are more jammers than the number of antennas. The performance of this non-linear beamforming technique is compared with well-known method Minimum Variance Distortionless Response (MVDR) Beamformer. An algorithm which enhances MVDR Performance in the scenario of more-jammers-than-antennas has been proposed. The beamformer methods are compared in a variety of scenario in order to outline the advantages and disadvantages clearly.

Performance of a non-linear adaptive beamformer algorithm for signal-of-interest extraction /
Oğuz, Özkan; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2015)

This method uses projections over convex sets in Reproducing Kernel Hilbert Space.

Estimation of the Hurst parameter for fractional Brownian motion using the CMARS method
Yerlikaya-Ozkurt, F.; Vardar Acar, Ceren; Yolcu-Okur, Y.; Weber, G. -W. (2014-03-15)
In this study, we develop an alternative method for estimating the Hurst parameter using the conic multivariate adaptive regression splines (CMARS) method. We concentrate on the strong solutions of stochastic differential equations (SDEs) driven by fractional Brownian motion (fBm). Our approach is superior to others in that it not only estimates the Hurst parameter but also finds spline parameters of the stochastic process in an adaptive way. We examine the performance of our estimations using simulated tes...
Consideration of spatial variation of the length scale parameter in static and dynamic analyses of functionally graded annular and circular micro-plates
Eshraghi, Iman; Dağ, Serkan; Soltani, Nasser (2015-09-01)
This article introduces new methods for static and free vibration analyses of functionally graded annular and circular micro-plates, which can take into account spatial variation of the length scale parameter. The underlying higher order continuum theory behind the proposed approaches is the modified couple stress theory. A unified way of expressing the displacement field is adopted so as to produce numerical results for three different plate theories, which are Kirchhoff plate theory (KPT), Mindlin plate t...
Performance comparisons of seismic assessment methods with PSD test results of a deficient RC frame
Ozcebe, G.; KURT, ELİF; Binici, Barış; Kurç, Özgür; Canbay, Erdem; Akpinar, U. (2009-12-01)
The accuracy of estimating the performance levels of a deficient RC frame using linear elastic and nonlinear dynamic analysis is evaluated in this study. This was achieved by comparing the response of a structure tested with pseudo-dynamic testing and estimated by the linear elastic assessment procedures along with nonlinear dynamic analysis. The test structure (three bay-two storey planar frame) is a 1/2 scale reinforced concrete frame having masonry infill walls in the central span. The test frame contain...
Performance of DOM and IDA with different angular discretization methods in 3-D absorbing-emitting-scattering media
Ozen, Guzide; Selçuk, Nevin (2013-03-01)
Predicted accuracy and computationally efficiency of Discrete Ordinates Method (DOM) and Improved Differential Approximation (IDA) were evaluated by applying both methods to cubical enclosure problems containing purely isotropically/linearly anisotropically scattering/absorbing-emitting-isotropically scattering medium and comparing their predictions with benchmark solutions available in the literature. Performances of DOM and IDA with S-8, S-10 and T-4 quadratures were assessed by comparing their prediction...
