Presents a study on the design and evaluation of two block coded modulation systems. One of the systems uses a binary construction and quadrature amplitude modulation. The other utilizes a ternary construction and phase modulation. The performance of the two coded schemes are compared theoretically with those of uncoded schemes of the same bandwidth, average power and transmission rate. The ternary scheme is also evaluated practically by computer simulations. Furthermore, the sub-optimum detection algorithm which is used in the ternary scheme is surveyed from the computational complexity and the memory requirement viewpoints.


Control electronics for mems gyroscopes and its implementation in a CMOS technology
Eminoğlu, Burak; Akın, Tayfun; Department of Electrical and Electronics Engineering (2011)
This thesis, for the first time in literature, introduces a comprehensive study about analog controller designs for MEMS vibratory gyroscopes. A controller of a MEMS gyroscope is mandatory for robust operation, which is insensitive to sensor parameters and ambient con- ditions. Errors in the controller design not only deteriorate transient performance, such as settling time and overshoot, but also cause performance degradation due to stability problems. Accordingly, true controller design for a gyroscope is...
Design, fabrication and implementation of a vibration based mems energy scavenger for wireless microsystems
Sarı, İbrahim; Balkan, Raif Tuna; Department of Mechanical Engineering (2008)
This thesis study presents the design, simulation, micro fabrication, and testing steps of microelectromechanical systems (MEMS) based electromagnetic micro power generators. These generators are capable of generating power using already available environmental vibrations, by implementing the electromagnetic induction technique. There are mainly two objectives of the study: (i) to increase the bandwidth of the traditional micro generators and (ii) to improve their efficiency at low frequency environmental v...
Analysis and Design of Multichannel Systems for Perceptual Sound Field Reconstruction
De Sena, Enzo; Hacıhabiboğlu, Hüseyin; Cvetkovic, Zoran (2013-08-01)
This paper presents a systematic framework for the analysis and design of circular multichannel surround sound systems. Objective analysis based on the concept of active intensity fields shows that for stable rendition of monochromatic plane waves it is beneficial to render each such wave by no more than two channels. Based on that finding, we propose a methodology for the design of circular microphone arrays, in the same configuration as the corresponding loudspeaker system, which aims to capture inter-cha...
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...
Analysis of extended feature models with constraint programming
Karataş, Ahmet Serkan; Oğuztüzün, Mehmet Halit S.; Department of Computer Engineering (2010)
In this dissertation we lay the groundwork of automated analysis of extended feature models with constraint programming. Among different proposals, feature modeling has proven to be very effective for modeling and managing variability in Software Product Lines. However, industrial experiences showed that feature models often grow too large with hundreds of features and complex cross-tree relationships, which necessitates automated analysis support. To address this issue we present a mapping from extended fe...
