Peer-to-peer relay technique provides the opportunity of cooperative communication
between users to achieve the transmission diversity. In this paper, the problem of relay …

In this paper, we investigate the joint optimization of power allocation and subcarrier
assignment in the OFDM bidirectional systems where two users exchange data assisted by …

Egitim hayatımın çok önemli bir sürecinde birlikte çalısma fırsatı buldugum, bilime ve bilimsel
arastırmacıya sınırsız destek veren Prof. Dr. Bekir Sıddık Binboga YARMAN gibi büyük bir …

In this paper, we study the problem of joint resource allocation in the two-way relay system,
where a pair of multi-antenna users wish to exchange information via multi-antenna amplify …

In this paper, we invoke sub-carrier pairing based sum-rate maximization problem in
wireless cooperative networks. Two-way relaying (TWR) with amplify-and-forward (AF) …

In cognitive radio networks, primary users can share some licensed spectrums with
secondary users in exchange for cooperation. In this study, an overlay scenario is …

Data transmission with low losses and dispersion is one of the biggest challenges for optical
communication. Light should be transmitted through a fiber that has the most optimum …

Relay-based cooperative wireless networks are considered one of the cost-effective
solutions to meet the demands in future wireless networks. In this paper, we address the …

In this paper, we study a cognitive two-way relay network in which orthogonal frequency
division multiplexing (OFDM) technique is adopted within the secondary system and a pair …

The Radio resource sensing is a basic requirement of a Cognitive-radio Networks, where
secondary users must ensure before they transmit, that the spectrum is not being used by …
