Graph optimized locality preserving projection via heuristic optimization algorithms
(Institute of Electrical and Electronics Engineers Inc., 2019)
Dimensionality reduction has been an active research topic in hyperspectral image analysis due to complexity and nonlinearity of the hundreds of the spectral bands. Locality preserving projection (LPP) is a linear extension ...
Orthogonal frequency division multiplexing with index modulation
(2012)
In this paper, a novel orthogonal frequency division multiplexing (OFDM) scheme, which is called OFDM with index modulation (OFDM-IM), is proposed for frequency-selective fading channels. In this scheme, inspiring from the ...
Indoor positioning using federated Kalman Filter
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this paper, one of the multi sensor fusion techniques, namely Federated Kalman Filter (FKF) performance is studied for Indoor Positioning problem. Kalman Filters having centralized and decentralized structures are widely ...
Flow structure in a mixing layer developing over flat bed at high reynolds numbers
(CRC Press/Balkema, 2016)
Results of a high resolution Detached Eddy Simulation (DES) are used to characterize the evolution of a shallow mixing layer developing between two parallel streams in a long open channel with a flat bed at a high Reynolds ...
Classification of ADHD using ensemble algorithms with deep learning and hand crafted features
(Institute of Electrical and Electronics Engineers Inc., 2019)
Attention Deficit Hyperactivity (ADHD) is a common neurodevelopmental disorder that typically appears in early childhood. Methods developed for diagnosing gives different results at different times. This is a major obstacle ...
Primary user detection in IEEE 802.15.4a based wireless sensor networks
(2013)
Ultra wideband impulse radio (UWB-IR) technology has been defined in the IEEE 802.15.4a standard for location and ranging applications. In this paper, UWB-IR sensors are considered in wireless sensor networks (WSNs) with ...
Space time coded cooperative communication with joint antenna and relay selection
(2010)
Although multiple antenna and cooperative communication techniques can increase the system capacity, it can be difficult to use them in practice because of their high complexity. In this paper," joint transmit/receive ...
Spline based channel estimation for STBC-SM systems over fast-varying rician fading channels
(Institute of Electrical and Electronics Engineers Inc., 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 ...
Busy tone implementation for coexistence of IEEE 802.22 and 802.11af systems
(Institute of Electrical and Electronics Engineers Inc., 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 ...
Modeling of visible light channels and performance analysis of ACO-OFDM
(Institute of Electrical and Electronics Engineers Inc., 2015)
Spectrum scarcity of traditional radio communication has led communication engineers to find new alternatives. Indoor visible light communication is one alternative to solve this problem since its spectrum is not regulated ...
