On achieving reduced error propagation sensitivity in DFE design via convex optimization
Digital TV receiver error rate transmission
2015/8/11
Decision Feedback Equalization (DFE) is expected in digital TV receivers and other high error rate environments. Error propagation usually occurs in infrequent bursts. It is argued here that the minim...

2011/3/22
In this paper, the wave propagation characteristics of single-phase medium voltage (MV) cross-linked polyethylene (XLPE) power cable are determined using time domain reflectometry (TDR) measurement te...
Radiowave propagation studies in tunnels using ADI-PE technique
Applied sciences Alternating direction implicit Radiowave propagation Tunnels
2014/11/7
Due to the growth of mobile communication systems, there is an increasing demand for numerical techniques capable of predicting signal strength in subway, railway and underground road tunnels. In this...
Experimental Observation of Oscillating Wave Propagation on Switch Lines for Generation of Continuous Electromagnetic Waves
Oscillating Wave Propagation Switch Lines Continuous Electromagnetic Waves
2009/9/4
We report the experimental observation of the generation of continuous electrical waves in a switch line, which is a transmission line periodically loaded with electronic switches. The oscillating mot...
Nondiffracting Light Beams of Long Range Propagation
Light beam Nondiffracting beam Long range propagation
2009/6/8
An unusual light beam, long range nondiffracting beam (LRNB) is presented. The LRNB propagates over a long range keeping its narrow beam width as if it does not diffract, while general light beams spr...
THE INFLUENCE OF NON-HOMOGENOUS DIELECTRIC MATERIAL IN THE WAVEGUIDE PROPAGATION MODES
Electromagnetic surface waves waveguide Dielectric waveguides Rectangular waveguides
2010/1/12
The aim of this paper is to indicate the equations of electromagnetic wave in homogenous and non-homogenous dielectric material, estabilising the bundary conditions and solves by FEM the equations of ...
