Robust Digital Watermarking Based on the Log-Polar Mapping 

Ridzon, R.; Levicky, D. (Společnost pro radioelektronické inženýrství, 2007-12)
The geometrical attacks are still an open problem for many digital watermarking algorithms used in present time. Most of geometrical attacks can be described by using affine transforms. This article deals with digital ...

Multi-Carrier Modulation and MIMO Principle Application on Subscriber Lines 

Vodrazka, J. (Společnost pro radioelektronické inženýrství, 2007-12)
The multi-carrier modulation is used in many applications, primary for a wireless transmission, for example Wi-Fi and WiMAX networks or DVB-T. But the same physical principle can be used also for metallic lines in access ...

Evaluation of Measurement Performance in Averaging Quantization System with Noise 

Kamensky, M.; Kovac, K.; Kralikova, E.; Krammer, A. (Společnost pro radioelektronické inženýrství, 2007-12)
Statistical description of quantization process is common in the theory of quantization. For the case of nonsubtractive dither theoretical analyses of the dithered quantizer have been confronted with experimental results. ...
