A cooperative communication approach to cognitive radio
(Işık Üniversitesi, 2011-09-12)
Cognitive radio, whose main idea is to have intelligent devices utilize the linı- ited resources, such as frequency spectrum in wireless channels, is becoming a groundbreaking technology. The aim of this thesis is to apply ...
Implementation of cooperative diversity in space frequency coded OFDM system
(Işık Üniversitesi, 2007)
Wireless technology is becoming an important part of our daily life. Although earlier wireless technologies were developed to provide voice transmission which did not require large amount of bandwidth, we are now equipped ...
Battery test and management system
(Işık Üniversitesi, 2019-05-28)
This thesis is about meeting and answering the needs of devices with batteries for battery testing and management. The goal of the battery test and management's is to use the full capacity of the device and to be able to ...
Evaluation of feature selection and encoding methods fpr superpixel image parsing
(Işık Üniversitesi, 2017-12-14)
This thesis is about image parsing which is one of the important problems in computer vision. The goal of image parsing is segmentation of object and labeling of each object. Recently, a popular way of image segmentation ...
Deep learning techniques for building density estimation from remotely sensed imagery
(Işık Üniversitesi, 2019-04-05)
This thesis is about point-wise estimation of building density on the remote sensing optical imageries by applying deep learning methods. The goal of the project is to reduce mean square error of the estimated density by ...
Compression of the mammography images using quadtree based energy and pattern blocks
(Işık Üniversitesi, 2017-01-16)
Medical images, like any other digital data, require compression in order to reduce disk space needed for storage and time needed for transmission. This thesis offers , a novel image compression method based on generation ...
Enhancement of the coded speech using filtering
(Işık Üniversitesi, 2017-04-14)
The processing and storage of speech signals are widely implemented in modern communication systems. Decreasing the amount of information for modeling the reconstruction of speech signal enhances the transmission and storage ...
Biometric recognition using bio-signals
(Işık Üniversitesi, 2017-04-14)
The main objective of the project is to increase the recognition rate by establishing a multimodal biometric recognition system that uses two di_erent biometric characteristics, as bio-signals. Today, institutions use ...
Data compression for smart grid infrastructure
(Işık Üniversitesi, 2018-01-15)
Embedded systems, which work with large data sets, need larger memory and consume much more data traffc when compared to other IOT (Interne Of Things) devices. In this study, Human's Lossless Compression Algorithm is ...
A new model for speech compression
(Işık Üniversitesi, 2021-19-10)
This thesis aims to propose a new low bit-rate speech compression method. In the proposed method, classical SYMPES (Systematic Procedure for Predefined Envelope and Signature Sequences) based predefined signature and ...
