Blind channel estimation for space-time coding systems with Baum-Welch algorithm
(IEEE, 2002)In recent years, space-time coding is proposed to provide significant capacity gains over the traditional communication systems in fading wireless channels. In this paper, we consider the problem of blind estimation of the ... -
Cyclostationarity based blind block timing estimation for alamouti coded MIMO signals
(IEEE, 2017-06)Blind parameter estimation algorithms provide a powerful tool for application scenarios where the use of training or pilot sequences is not desirable, e.g., in order to improve the bandwidth efficiency of the transmission, ... -
Enerji depolama kayıpları altında enerji hasat eden işbirlikli çoklu erişim
(IEEE, 2017-06-27)Bu bildiride, enerji hasat eden iki vericiyle bir alıcının haberleştiği işbirlikli bir çoklu erişim kanalı için, sonlu batarya sığası ve enerji depolama kayıpları altında ulaşılabilir gönderim bölgesi eniyileme problemini ... -
On the effects of random timing jitter on spectrum sensing algorithms based on cyclostationarity
(IEEE, 2009)Cognitive radio is an enabling technology, which is expected to lead to a more efficient utilization of the available spectral resources due to its flexibility and its ability to sense its spectral environment. Recently, ... -
Optimum power control for transmitter cooperation in OFDMA based wireless networks
(IEEE, 2011)For a cooperative orthogonal frequency division multiple access (OFDMA) system with two transmitters (TXs), and full channel state information (CSI), we obtain the optimal power allocation (PA) policies which maximize the ... -
Power control in the cognitive cooperative multiple access channel
(IEEE, 2012)We extend several encoding and decoding techniques from cooperative communications framework, to a cognitive radio system consisting of a primary user (PU) and a secondary user (SU), sending their messages to a common ...
