Channel estimation in underwater cooperative OFDM system with amplify-and-forward relaying
(IEEE, 2012)
This paper is concerned with a challenging problem of channel estimation for amplify-and-forward cooperative relay based orthogonal frequency division multiplexing (OFDM) systems in the presence of sparse underwater acoustic ...
Prediction of the monomer-monomer ınterface region of the beta 2Ar homo-dimer receptor via docking experiments
(Cell Press, 2012)

Social media integration in higher education cross-course google plus integration shown in the example of a master's degree course in management
(Elsevier Science Bv, 2012)
Nearly all web services can be adapted for educational use Although some nistructors do use social media for their courses privacy concerns always throttle the 'need' of instructors for social media. Google Plus seems to ...
Performance of IEEE 802.15.4a Systems in the Presence of Narrowband Interference
(IEEE, 2011)
The regulatory agencies in Europe and Japan require the implementation of avoidance techniques in some bands to reduce interference to licensed systems. Accordingly ultra-wideband impulse radio (UWB-IR) based Wireless ...
The Effect of Channel Models on Compressed Sensing Based UWB Channel Estimation
(IEEE, 2011)
Ultra-wideband (UWB) multipath channels are assumed to have a sparse structure as the received consecutive pulses arrive with a considerable time delay and can be resolved individually at the receiver. Due to this sparse ...
Performance Investigation of IEEE 802.11af Systems Under Realistic Channel Conditions
(IEEE, 2015)
As the analog TV broadcasting channels have become less frequently used in the last decade there has been a great interest in these frequency bands for the deployment of metropolitan local and personal area networks. Among ...
Busy Tone Implementation for Coexistence of IEEE 802.22 and 802.11 af Systems
(IEEE, 2015)
In this paper a new algorithm based on busy tone approach has been proposed for the coexistence of IEEE 802.22 and IEEE 802.11af systems in TV white space. Different from the earlier study in addition to 802.11af access ...
Spline Based Channel Estimation for STBC-SM Systems over Fast-Varying Rician Fading Channels
(IEEE, 2015)
In the STBC-SM systems the information is carried both by STBC symbols and indices of the transmit antennas from which these symbols are transmitted. Channel estimation is a critical process at the receiver during the ...
Power Control-Based Multi-User Li-Fi Using A Compound Eye Transmitter
(IEEE, 2015)
In visible light communications (VLC) the transmitted signal is non-negative and real valued and these characteristics constrain the signal space and provide new challenges for waveform design in a multi-user system. In ...
