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 ...
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 ...
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 ...
Prosodic, morphological and lexical feature extraction of Turkish broadcast news data
(Işık Üniversitesi, 2014-06-05)
Sentence segmentation from speech is part of a process that aims at enriching the unstructured stream of words that are the output of standard speech recognizers. Its role is to find the sentence units in this stream of ...
Fingertip ECG signal based biometric recognition system
(Işık Üniversitesi, 2016-05-10)
The idea is the; realize biometric recognition system by using ECG signal which was began to use in the last 10 years. Until now, ECG based biometric systems have been developed by using the database which ECG signals are ...
Compress and forward based cooperation strategies in wireless networks
(Işık Üniversitesi, 2011-09-09)
Cooperative Communications are emerging as an alternative technology to MIMO Communications. In this thesis, we first summarize information theoretical anal- ysis of known channel types and also consider three fundamental ...
Measurement of sea water parameters using mems technology
(Işık Üniversitesi, 2012-02-08)
The system is used to measure the pressure and the temperature values up to hundred meters of the sea water. This project is also called as expendable environmental probe. The probe contains a temperature sensor, a pressure ...
