Achieving the capacity region boundary of fading CDMA channels via generalized iterative waterfilling
Kaya, Onur; Ulukuş, Şennur (IEEE, 2006-11)We characterize the optimum power control policies that achieve arbitrary rate tuples on the boundary of the, capacity region of a power controlled, code division multiple access (CDMA) system in a fading channel with ... -
Cognitive cooperative MAC with one primary and two secondary users: achievable rates and optimal power control
Edemen, Çağatay; Kaya, Onur (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 ... -
Cooperative strategies and achievable rates for two user OFDMA channels
Bakım, İsmail Sezi; Kaya, Onur (IEEE-INST Electrical Electronics Engineers Inc, 2011-12)We propose three encoding strategies for a two user cooperative Orthogonal Frequency Division Multiple Access (OFDMA) system, based on block Markov superposition encoding (BMSE). We obtain the expressions for the resulting ... -
Energy and data cooperative multiple access channel with intermittent data arrivals
Gürakan, Berk; Kaya, Onur; Ulukuş, Şennur (IEEE, 2018-03)We consider an energy harvesting two user cooperative Gaussian multiple access channel, where both of the users harvest energy from nature. The users cooperate at the physical layer (data cooperation) by establishing common ... -
Enerji hasadı yapan kablosuz ağlarda kullanıcı işbirliği ve kaynak tahsisi
Kaya, Onur; Ulukuş, Şennur (Tübitak, 2016-11)Yeni nesil haberleşme sistemlerinde, pillere ya da şehir elektriğine bağımlı olarak çalışan klasik haberleşme bileşenlerinin yerlerini, enerjilerini çevreden hasat eden, çevreye duyarlı ve uzun kullanım ömrüne sahip ... -
İşbirlikçi bilişsel radyo sistemleri için kodlama ve kod çözme teknikleri, erişilebilir veri hızları ve kaynak tahsisi
Kaya, Onur; Bakşi, Saygın; Edemen, Çağatay (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 ... -
Power allocation for cooperative communications
Kaya, Onur; Ulukuş, Şennur (IGI Global, 2009)In this chapter, we review the optimal power allocation policies for fading channels in single user and multiple access scenarios. We provide some background on cooperative communications, starting with the relay channel, ... -
Power control for fading cooperative multiple access channels
Kaya, Onur; Ulukuş, Şennur (IEEE, 2007-08)For a fading Gaussian multiple access channel with user cooperation, we obtain the power allocation policies that maximize the average rates achievable by block Markov superposition coding, subject to average power ... -
Power control for two user cooperative OFDMA channels
Bakım, İsmail Sezi; Kaya, Onur (IEEE-INST Electrical Electronics Engineers Inc, 2013-01)For a two user cooperative orthogonal frequency division multiple access (OFDMA) system with full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the rate region achievable ...
