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 ...
Cooperative strategies, achievable rates and resource allocation for OFDMA channels
(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 ...
New approaches for channel estimation in wireless communications
(Işık Üniversitesi, 2006-03-10)
This thesis first proposes a conputationally efficient, pilot-aided linear minimum mean square error (MMSE) batch channel estimation algorthm for the orthogonal frequency division multiplexing OFDM systems in unkonown ...
