Design and optimization of multiuser cooperative protocols for wireless networks
(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 ...
İşbirlikçi bilişsel radyo sistemleri için kodlama ve kod çözme teknikleri, erişilebilir veri hızları ve kaynak tahsisi
(Tübitak, 2013-10-01)
İşbirlikli iletişim ve bilişsel radyo, yeni nesil kablosuz haberleşme ağlarında kapasite ve iletişim kalitesinin artırımı için kilit tekniklerdir. Bu tekniklerin her ikisi de, çevrelerinin farkında olan ve bu farkındalığı ...
Cognitive cooperative MAC with one primary and two secondary users: achievable rates and optimal power control
(IEEE-INST Electrical Electronics Engineers Inc, 2014-11)
We consider a three-user fading cognitive cooperative multiple access channel (MAC) with one primary and two secondary transmitters. We propose two encoding/decoding strategies with varying levels of cooperation, based on ...
A new block Markov coding strategy for pairwise and collective cooperation in the three user MAC
(IEEE, 2013)
For a three user cooperative multiple access channel (MAC), we propose a new block Markov superposition encoding strategy, which enables all three users to cooperate collectively as well as in pairs. We obtain the resulting ...
Radio resource management for OFDMA-based mobile relay enhanced heterogenous cellular networks
(IEEE, 2013)
In this paper, we focus on the radio resource management problem for the Orthogonal Frequency Division Multiple Access (OFDMA)-based mobile relay-enhanced het erogenous cellular networks. We combine mobile relaying and ...
