Channels estimation in OFDM system on block-type and comb-type pilot arrangement
(Universiti Malaysia Perlis (UniMAP), 2012-06-18)
In orthogonal frequency division multiplexing (OFDM) systems over time-varying and frequency-selective fading channel, channel estimation and tracking is generally carried out by transmitting known pilot symbols in given ...
Modeling and simulation of WSNs for agriculture applications using dynamic transmit power control algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02)
Simulation platforms have become important tools in the design and evaluating of protocols for Wireless Sensor Networks. Thus the use of realistic models in simulation is important for the development of protocols. However, ...
Vision-based motion tracking rehabilitation system for gait disorder
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
Aim of the present study was to review the articles for the vision-based motion tracking, usually applied on the rehabilitation systems of gait disorder. Based on our ultimate goal, we searched several articles, available ...
High deadline meeting rate of non-preemptive dynamic soft real time scheduling algorithm
(Institute of Electrical and Electronics Engineers (IEEE), 2012-11)
Hard real time systems were often implemented with preemptive scheduling, which gives priority to the highest priority task. In this paper we present a new non-preemptive scheduling of jobs meant for soft real time ...
Synthesis of finite length multi level sequences for clutter rejection in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-07-24)
In radar systems the very low side-lobes that can be achieved with amplitude and phase modulated pulse trains make their use particularly attractive in systems requiring a large dynamic range. Moreover, the excellent ...
Waveform design for improved range and Doppler resolution in radar
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02)
The choice of a suitable transmit waveform is an important problem in radar design. This is so because the waveform controls resolution and clutter performance and also bears heavily on the system cost. Theoretical studies ...
Characteristic region based image steganography using Speeded-Up Robust Features technique
(Institute of Electrical and Electronics Engineers (IEEE), 2012)
Steganography is the art and science of invisible
communication. It is employed in different useful a
pplications,
like, safe circulation of secret data and Medical I
maging Systems.
For most of the current steganography ...
