An equivalent circuit model for a typical commercial light-emitting diode (LED) used in visible light communication (VLC) applications is proposed. The parameters of the elements are extracted from measured impedance using vector network analyser. shows high accuracy fitting results and effect bonding/packaging parasitics electrostatic discharge (ESD) component on LED's bandwidth. This study ai...

We describe a method to automatically extract a German lexicon from Wiktionary that is compatible with the finite-state morphological grammar SMOR. The main advantage of the resulting lexicon over existing lexica for SMOR is that it is open and permissively licensed. A recall-oriented evaluation shows that a morphological analyser built with our lexicon has comparable coverage compared to exist...

In this paper, a novel wavelet-based detection algorithm is introduced for the detection of chipless RFID tags. The chipless RFID tag has a frequency signature which is identical to itself. Here a vector network analyser is used where the received backscatter signal is analysed in frequency domain. Thus the frequency signature is decoded by comparing the wavelet coefficients which identifies th...
