Channel adaptive user cooperation strategies for fading wireless channels
Edemen, Çağatay (Işık Üniversitesi, 2006)In this dissertation, a channel adaptive method is proposed for a two user halfduplex cooperative communication system under the assumption of perfect channel state information at the transmitters and the receiver. An ... -
Compress and forward based cooperation strategies in wireless networks
Güneş, Mehmet (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 ... -
A cooperative communication approach to cognitive radio
İşleyen, Murat (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 ... -
Cooperative strategies, achievable rates and resource allocation for OFDMA channels
Bakım, İsmail Sezi (Işık Üniversitesi, 2011-07-28)The design of next generation wireless communication systems brings along new challenges, since the degrading factors such as fading and multi-user interference become harder to deal with as the number of users and the ... -
Design and optimization of multiuser cooperative protocols for wireless networks
Edemen, Çağatay (Işık Üniversitesi, 2014-09-12)Recently, the main trend in wireless communications has shifted from voice transmission to data communication. Naturally, this shift caused an increase in the data rate and bandwidth requirements. Being a limited and thus ... -
Energy and data cooperation in energy harvesting multiple access channels
Şişman, Berrak (Işık Üniversitesi, 2016)A typical wireless device is limited by its nite battery, and energy limitation is as a critical bottleneck on wireless network performance. In addition to the EM radiation caused by high power wireless devices, the ... -
Implementation of cooperative diversity in space frequency coded OFDM system
Yiğit, Can (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 ... -
Partner selection and resource allocation in single-cell, multi-cell and cognitive cooperative multiple access channels
Bakşi, Saygın (Işık Üniversitesi, 2013-06-06)Wireless communication has been widely used across the globe for several years. As the technology advances and gains popularity, more people start using it and more throughput is needed. For that reason, several techniques ...
