Low-complexity joint data detection and channel equalisation for highly mobile orthogonal frequency division multiplexing systems
(2010)
This study is concerned with the challenging and timely problem of channel equalisation and data detection for orthogonal frequency division multiplexing (OFDM) systems in the presence of frequency-selective and very rapidly ...
An integrated model for visualizing biclusters from gene expression data and PPI networks
(2010)
We provide a model to integrate the visualization of biclusters extracted from gene expresion data and the underlying PPI networks. Such an integration conveys the biologically relevant interconnection between these two ...
Synthesis of lossless ladder networkswith simple lumped elements connected viacommensurate transmission lines
(Istanbul University, 2010)
An algorithm has been proposed to synthesize low-pass high-pass band-pass and band-stop lossless ladder networks with simple lumped elements connected via commensurate transmission lines (Unit elements UEs). First the type ...
Sparse underwater acoustic channel estimation in colored Gaussian noise [Renkli? Gauss gürültülü seyrek sualtı akusti?k kanalların kestirimi]
(IEEE, 2012)
Cooperative underwater acoustic communication systems come into prominence in recent years. Since underwater channels are sparse and additive noise entering the system is colored Gaussian noise. Therefore it is very difficult ...
Double branch outage modeling and its solution using differential evolution method
(2011)
Power system operators need to check the system security by contingency analysis which requires power flow solutions repeatedly. AC power flow is computationally slow even for a moderately sized system. Thus fast and ...
Space time turbo coded OFDM system with transmit and receive antenna selection
(IEEE, 2011)
In this paper a space-time turbo coded (STTC) orthogonal frequency division multiplexing (OFDM) system with QPSK signalling is explored when joint transmit and receive antenna selection is employed. Maximization of signal ...
Realization of ideal filter characteristics via genetic algorithm
(2011)
In this paper realization of ideal filter characteristics via genetic algorithm has been studied. The filter is defined as a lossless two-port terminated normalized source and load resistances and the coefficients of its ...

Model based predictive rate controller for video streaming
(2009)
Due to the heterogeneous structure of networks video streaming over lossy IP networks is very important issues. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ...
Thyroid and breast cancer disease diagnosis using Fuzzy-neural networks
(2009)
In this paper a new hybrid structure in which Neural Network and Fuzzy Logic are combined is proposed and its algorithm is developed. Fuzzy-CSFNN Fuzzy-MLP and Fuzzy-RBF structures are constituted and their performances ...
