This study concentrates on the performance evaluation of a specific modulation scheme under nonlinear operation. This modulation scheme is the phase shift keying (PSK) modulation, exemplified by the special cases of BPSK, QPSK, OQPSK, p/4-QPSK. The specific nonlinear block is chosen to be the solid state power amplifier (SSPA) structure whose simulation model is the Rapp model. Varying transmitter filter characteristic and one of the power amplifier parameters constitute the main methodology of simulations. Bit error rate (BER), error vector magnitude (EVM), and Space Frequency Coordination Group (SFCG) spectral mask constraint are the evaluation parameters taken into account throughout this study. Simulation results support the initial literature survey, which reveals additional features showing how each modulation scheme is affected by various SSPA nonlinearity characteristics.

Investigation of music algorithm based and wd-pca method based electromagnetic target classification techniques for their noise performances Ergin, Emre; Sayan, Gönül; Department of Electrical and Electronics Engineering (2009) Multiple Signal Classification (MUSIC) Algorithm based and Wigner Distribution-Principal Component Analysis (WD-PCA) based classification techniques are very recently suggested resonance region approaches for electromagnetic target classification. In this thesis, performances of these two techniques will be compared concerning their robustness for noise and their capacity to handle large number of candidate targets. In this context, classifier design simulations will be demonstrated for target libraries con...
Effect of stacking sequence on free vibration frequencies of laminated composite circular cylindrical shells Kayran, Altan (SAGE Publications, 1999-05-01) This study compares the effect of stacking sequence on natural frequencies of cylindrical shells for different end conditions and vibration modes. For this purpose, an analysis of the natural frequencies of laminated composite cylindrical shells is carried out using linear Reissner shell theory with the transverse shear deformation effects taken into account. The governing equations for the free vibration of laminated cylindrical shells are reduced to 10 first-order differential equations involving 10 unkno...
Measurement of prompt J/psi pair production in pp collisions at root s = 7 Tev Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2014-09-01) Production of prompt J/psi meson pairs in proton-proton collisions at root s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb(-1). The two J/psi mesons are fully reconstructed via their decays into mu(+)mu(-) pairs. This observation provides for the first time access to the high-transverse-momentum region of J/psi pair production where model predictions are not yet established. The total and differential cross sections are meas...
Optimum current injection strategy for magnetic resonance electrical impedance tomography Altunel, Haluk; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2008) In this thesis, optimum current injection strategy for Magnetic Resonance Electrical Impedance Tomography (MREIT) is studied. Distinguishability measure based on magnetic flux density is defined for MREIT. Limit of distinguishability is analytically derived for an infinitely long cylinder with concentric and eccentric inhomogeneities. When distinguishability limits of MREIT and Electrical Impedance Tomography (EIT) are compared, it is found that MREIT is capable of detecting smaller perturbations than EIT. ...
Noise reduction in time-frequency domain Kalyoncu, Özden; SÜnver, Zafer; Department of Electrical and Electronics Engineering (2007) In this thesis work, time-frequency filtering of nonstationary signals in noise using Wigner-Ville Distribution is investigated. Continuous-time, discrete-time and discrete Wigner Ville Distribution definitions, their relations, and properties are given. Time-Frequency Peak Filtering Method is presented. The effects of different parameters on the performance of the method are investigated, and the results are presented. Time-Varying Wiener Filter is presented. Using simulations it is shown that the performa...
