Design and performance analysis of a novel trellis coded space-time-frequency OFDM transmission scheme
(Wiley-Blackwell, 2008-01)
In this paper a new transmit diversity technique is proposed for wireless communications over frequency selective fading channels. The proposed technique utilises orthogonal frequency division multiplexing (OFDM) to transform ...
Modulation of nonlinear waves in a thin elastic tube filled with a viscous fluid
(Pergamon-Elsevier Science Ltd, 1999-11)
In the present work, utilizing the nonlinear equations of a prestressed thin elastic tube filled with an incompressible viscous fluid the propagation of weakly nonlinear waves in such a medium is studied. Considering that ...
Optical design of the adaptive optics system for DAG, the new 4 m Turkish telescope
(SPIE, 2020)
We present the design of the Adaptive Optics System for the new Turkish 4-m telescope (DAG). The AO will use a pyramid WFS, with a double prism and a no noise EM-CCD camera to allow for oversampling of the pupil images and ...
Interactions of nonlinear acoustic waves in a fluid-filled elastic tube
(Pergamon-Elsevier Science, 2001-03)
In the present work, the nonlinear interactions of two acoustical waves propagating in a fluid-filled elastic tube with different wave numbers, frequencies and group velocities are examined. Employing the multiple-scale ...
On the performance of trellis coded M-PSK systems over Rician fading channels with phase jitter
(Assoc Elettrotecnica Ed Elettronica Italiana, 2001-02)
In this paper, the performance of trellis coded M-PSK systems is investigated operating over Rician fading channels with phase jitter. Thus the results reflect not only the degradation due to the effect of fading on the ...
A higher-order model for transverse waves in a generalized elastic solid
(Pergamon-Elsevier Science, 2002-11)
In the present study, the nonlinear modulation of transverse waves propagating in a generalized elastic solid is studied using a multi-scale expansion of quasi-monochromatic wave solutions. In particular, to include the ...
Automatic modulation classification for mimo systems using fourth-order cumulants
(IEEE, 2012)
Automatic classification of the modulation type of an unknown communication signal is a challenging task, with applications in both commercial and military contexts, such as spectrum surveillance, cognitive radio, and ...
MIMO sinyalleri için uzay-zaman blok kodu klasifikasyonu

Resource allocation in the finite blocklength regime under PAoI and delay violation constraints
(IEEE, 2023-08-27)
URLLC (Ultra-reliable low-latency communication) is one of the more challenging modes for 5G for resource allocation (RA). Most of the previous studies for RA for wireless access in URLLC assumed known packet arrival ...
Joint modulation classification and antenna number detection for MIMO systems
(IEEE, 2016-01-07)
Noncooperative classification of the modulation type of communication signals finds application in both civilian and military contexts. Existing modulation classification methods for multiple-input multiple-output (MIMO) ...
