Blind Audio Watermarking in Transform Domain Based on Singular Value Decomposition and Exponential-Log Operations
(Společnost pro radioelektronické inženýrství, 2017-06)Digital watermarking has drawn extensive attention for copyright protection of multimedia data. This paper introduces a blind audio watermarking scheme in discrete cosine transform (DCT) domain based on singular value ... -
The Design and Analysis of Invisible Radome with Sandwich-like Properties
(Společnost pro radioelektronické inženýrství, 2017-06)A novel thin radome made by metamaterial is presented, with the properties like the sandwich where the middle acts as a pass band filter at an expected frequency band, while others behave as absorbers. This new radome ... -
2D DOA Estimation of UCA Correlative Interferometer Based on One Dimensional Sorting Lookup Table-Two Dimensional Linear Interpolation Algorithm
(Společnost pro radioelektronické inženýrství, 2017-06)In order to improve the direction-finding efficiency of the correlative interferometer and reduce the size of the lookup table, this paper proposes the one dimensional sorting lookup table-two dimensional linear interpolation ... -
Distributed Aggregate Function Estimation by Biphasically Configured Metropolis-Hasting Weight Model
(Společnost pro radioelektronické inženýrství, 2017-06)An energy-efficient estimation of an aggregate function can significantly optimize a global event detection or monitoring in wireless sensor networks. This is probably the main reason why an optimization of the complementary ...
