Achieving the targeted data rates for next generation wireless communication systems requires using frequency reuse ratio 1 in these systems, but this in turn results in significant intercell interference observed especially by the users near cell edges. Cooperation between the base stations plays an important role in reducing the intercell interference. In this paper, we consider the problem of cooperative data transmission from the base stations to the users in multicellular multiple input multiple output (MIMO) orthogonal frequency division multiple access (OFDMA) systems. We propose an efficient cooperative scheduling and data transmission scheme, requiring limited information exchange between the base stations. ©2009 IEEE.

Dardari, D.; Karisan, Y.; Gezici, S.; D'Amico, A.A.; Mengali, U. (2009)Cognitive radio is a promising paradigm for efficient utilization of the radio spectrum due to its capability to sense environmental conditions and adapt its communication and localization features. In this paper, the ...
Ali, S.; Markarian, G.; Arıkan, Erdal (IEEE, 2009)The RF amplifier in a wireless communication system is usually non-linear in nature. If such an amplifier is used in OFDMA based systems, it will cause serious degradation. This degradation will be both in terms of the ...
Degrees of freedom of optical systems and signals with applications to sampling and system simulation Oktem F.S.; Özaktaş, Haldun M. (Optical Society of America, 2013)We study the degrees of freedom of optical systems and signals based on space-frequency (phase space) analysis. At the heart of this study is the relationship of the linear canonical transform domains to the space-frequency ...
