Performance analysis of transmit and receive antenna selection over flat fading channels
(IEEE-INST Electrical Electronics Engineers Inc, 2008)The paper considers two different antenna selection schemes for space-time coded systems over flat fading channels. First we explore antenna selection at the transmitter side based on the received signal to noise ratios. ... -
Performance Improvement of Threshold Based Audio Steganography Using Parallel Computation
(Science & Information SAI Organization Ltd, 2016)Audio steganography is used to hide secret information inside audio signal for the secure and reliable transfer of information. Various steganography techniques have been proposed and implemented to ensure adequate security ... -
Performance Investigation of IEEE 802.11af Systems Under Realistic Channel Conditions
(IEEE, 2015)As the analog TV broadcasting channels have become less frequently used in the last decade there has been a great interest in these frequency bands for the deployment of metropolitan local and personal area networks. Among ... -
Performance of Distributed Estimation Over Unknown Parallel Fading Channels
(IEEE-INST Electrical Electronics Engineers Inc, 2008)We consider distributed estimation of a source in additive Gaussian noise observed by sensors that are connected to a fusion center with unknown orthogonal (parallel) flat Rayleigh fading channels. We adopt a two-phase ... -
Performance of IEEE 802.15.4a Systems in the Presence of Narrowband Interference
(IEEE, 2011)The regulatory agencies in Europe and Japan require the implementation of avoidance techniques in some bands to reduce interference to licensed systems. Accordingly ultra-wideband impulse radio (UWB-IR) based Wireless ... -
Performance of MIMO Enhanced Unipolar OFDM With Realistic Indoor Visible Light Channel Models
(Institute of Electrical and Electronics Engineers Inc., 2016)Visible light communication (VLC) involves the dual use of illumination infrastructure for high speed wireless access. Designing such optical based communication systems realistic indoor optical channel modeling becomes ... -
Performance of space time codes with transmit antenna selection over frequency selective fading channels in the presence of channel estimation errors
(2008)This paper presents a performance analysis of space-time coded systems with transmit antenna selection over frequency selective fading channels when the erroneously estimated fading coefficients are available only at the ... -
Performance of space-time coded systems with transmit antenna selection
(IEEE, 2007)We deal with transmit antenna selection for space-time coded (STC) systems over multiple input multiple output (MIMO) channels. Using pairwise error probability analysis and simulation results we show that transmit antenna ... -
Performance of spatial modulation in the presence of channel estimation errors
(IEEE-INST Electrical Electronics Engineers Inc, 2012)This work investigates the negative effects of channel estimation errors on the performance of spatial modulation (SM) when operating over flat Rayleigh fading channels. The pairwise error probability of the SM scheme is ... -
Performance of Stack Equalizer over Frequency Selective Fading Channels
(IEEE, 2008)In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational ... -

(2008)In this paper the performance of the low complexity modified stack equalizer over frequency-selective fading channels is inspected. With the help of simulation results it is illustrated that by sacrificing the computational ... -
The Performance of the RSS-Based Lateration Algorithm for Indoor Localization
(Institute of Electrical and Electronics Engineers Inc., 2019)Localization methods have evolved over the years and led the invention of the Global Positioning System for outdoor localization. In time, the need for indoor localization has also arisen and research on indoor positioning ... -
Performance of transmit and receive antenna selection in the presence of channel estimation errors
(IEEE-INST Electrical Electronics Engineers Inc, 2008)This letter considers the effect of channel estimation errors on the performance of space-time coded (STC) systems with transmit and receive antenna selection over quasi-static flat fading channels. By performing pairwise ... -
Personal and familial predictors of depressive feelings in people with orthopedic disability
(Termedia Publishing House, 2017)BACKGROUND People with orthopedic disability experience limitations in physical ability which can cause psychological problems such as depressive feelings. This paper investigates the role of family environment caregiver ... -
Personality and contextual antecedents of organizational citizenship behavior: A study of two occupational groups
(Cambridge Univ Press, 2014)This paper examines the impact of personality trait of dispositional affect and contextual variables of multiple commitments on organizational citizenship behaviors (OCBs) in two occupational groups. Three dimensions of ... -
The Personality and Leadership Style of Recep Tayyip Erdogan: Implications for Turkish Foreign Policy
(Routledge Journals Taylor & Francis Ltd, 2011)Recep Tayyip Erdog. an is clearly the most controversial figure in recent Turkish political history. His preponderance in political life is remarkable even by Turkish standards. Because Erdog. an is so powerful and has ... -
Personality Motivation and Math Achievement Among Turkish Students: Evidence from PISA Data

Pharmacophore-based virtual screening for identification of potential selective inhibitors of human histone deacetylase 6
(Elsevier Sci Ltd, 2018)Histone deacetylase (HDAC) 6 plays a role in oncogenic transformation and cancer metastasis via tubulin deacetylation, making it a critical target for anticancer drug design. However, lack of selectivity shown by many of ... -
Phase transitions between different spin-glass phases and between different chaoses in quenched random chiral systems
(Amer Physical Soc., 2017)The left-right chiral and ferromagnetic-antiferromagnetic double-spin-glass clock model with the crucially even number of states q = 4 and in three dimensions d = 3 has been studied by renormalization-group theory. We find ...
