An efficient algorithm for instantaneous frequency estimation of nonstationary multicomponent signals in low SNR
(2011 , Article)
A method for components instantaneous frequency (IF) estimation of multicomponent signals in low signal-to-noise ratio (SNR) is proposed. The method combines a new proposed modification of a blind source separation (BSS) ...
Joint interference cancellation and dirty paper coding for cognitive cellular networks
(2011 , Conference Paper)
Downlink communication in a cellular network with a cognitive (secondary) cell is considered. In our model, the base station of the cognitive cell knows the messages of the other cell non-causally. We propose a new ...
On the degrees of freedom of the cognitive broadcast channel
(2011 , Conference Paper)
Cognitive broadcast channel, where two multiantenna transmitters communicate with their respective receivers, is considered. One of the transmitters is said to be cognitive (secondary) as it is assumed to know the messages ...

Enhanced Alamouti decoding scheme for DVB-T2 systems in SFN channels
(
IEEE
, 2011 , Conference Paper)
The standard Alamouti space-frequency block code (SFBC) suffers from performance degradation when used over highly frequency-selective channels because the channel frequency response is not necessarily flat over the Alamouti ...
