Shape control of cyclic networks in multirobot formations
(Tubitak Scientific & Technical Research Council Turkey, 2013)
The first part of this paper examines cycles at the network level of sensing and control architectures that are needed to maintain the shape of a multiagent formation in 2-dimensional space, while the formation moves as a ...
Channel estimation based on neural network in space time block coded MIMO-OFDM system
(Academic Press Inc Elsevier Science, 2013)
In this study, we propose feed-forward multilayered perceptron (MLP) neural network trained with the Levenberg-Marquardt algorithm to estimate channel parameters in MIMO-OFDM systems. Bit error rate (BER) and mean square ...
A video-based eye pupil detection system for diagnosing bipolar disorder
(Tubitak Scientific & Technical Research Council Turkey, 2013)
Eye pupil detection systems have become increasingly popular in image processing and computer vision applications in medical systems. In this study, a video-based eye pupil detection system is developed for diagnosing ...
Minimal controller synthesis algorithms with output feedback and their generalization
(Tubitak Scientific & Technical Research Council Turkey, 2013)
This paper proposes several improvements in the minimal controller synthesis algorithms, which were developed for a class of nonlinear systems with uncertainties. The major proposition is that only the output feedback is ...
Pilot Tones Optimization Using Artificial Bee Colony Algorithm for MIMO-OFDM Systems
(Springer, 2013)
How to design the pilot tones that are used in channel estimation has a significant effect on the estimation performance. To achieve good performance in least square (LS) algorithm, we propose the artificial bee colony ...
Radial Basis Function Neural Networks for Channel Estimation in MIMO-OFDM Systems
(Springer Heidelberg, 2013)
Orthogonal frequency division multiplexing (OFDM) combined with multiple input multiple output (MIMO) antennas is one of the promising schemes for high rate data transmission and capacity improvement. However, in these ...
