A low-complexity time-domain MMSE channel estimator for space-time/frequency block-coded OFDM systems
(Hindawi Publishing Corporation, 2006)
Focusing on transmit diversity orthogonal frequency-division multiplexing (OFDM) transmission through frequency-selective channels this paper pursues a channel estimation approach in time domain for both space-frequency ...
An Integrated Software Architecture for Bandwidth Adaptive Video Streaming
(World Acad Sci Eng & Tech-Waset, 2008)
Video streaming over lossy IP networks is very important issues due to the heterogeneous structure of networks. Infrastructure of the Internet exhibits variable bandwidths delays congestions and time-varying packet losses. ...
Transmitter source location estimation using crowd data
(Pergamon-Elsevier Science Ltd, 2018)
The problem of transmitter source localization in a dense urban area has been investigated where a supervised learning approach utilizing neural networks has been adopted. The cellular phone network cells and signals have ...
Linear expansions for frequency selective channels in OFDM
(Elsevier GMBH Urban & Fischer Verlag, 2006)
Modeling the frequency selective fading channels as random processes we employ a linear expansion based on the Karhumen-Loeve (KL) series representation involving a complete set of orthogonal deterministic vectors with a ...
Optimizing NEURON Brain Simulator With Remote Memory Access On Distributed Memory Systems
(Institute of Electrical and Electronics Engineers Inc., 2016)
The Complex neuronal network models require support from simulation environment for efficient network simulations. To compute the models increasing complexity necessitated the efforts to parallelize the NEURON simulation ...
Nearest Fixed Clustering Algorithm (NFCA) for Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers Inc., 2016)
The objective of reducing energy consumption at the sensor nodes has become a key research area for wireless sensor networks (WSNs) in recent years. With the steady increase in the cost of energy the existing algorithms ...
Extending the lifetime of WSNs with Maximum Energy Selection Algorithm (MESA)
(Institute of Electrical and Electronics Engineers Inc., 2017)
The limited battery supply of a sensor node is one of the most important factors that limit the lifetime of the WSNs. As a consequence increasing the lifetime of WSNs through energy efficient mechanisms has become a ...
Multi-hop low energy fixed clustering algorithm (M-LEFCA) for WSNs
(Institute of Electrical and Electronics Engineers Inc., 2017)
The limited battery supply of sensor nodes is one of the most important factors which restrict the lifetime of the wireless sensor networks (WSNs). As a consequence the wide deployment of WSNs in the recent years led to ...
Competitive intelligence and information technology adoption of SMEs in Turkey: Diagnosing current performance and identifying barriers
(Halmstad University, 2013)
The need for SMEs to behave in a more concise and coherent competitive fashion is well recognised. This study reports on an empirical study of SMEs in Turkey. Their responses were applied to a behavioural and information ...
A synthesis tool for the multiplierless realization of FIR-based multirate DSP systems
(IEEE, 2000)
In this study a synthesis tool using a novel multirate folding technique which handles each FIR filter in a multirate DSP system as a single node is developed. A new architecture is presented for the multiplierless realization ...
