Robust spatial watermarking technique for colour images via direct saturation adjustment
TL;DR: A novel and robust colour watermarking approach for applications in copy protection and digital archives by hiding the watermark into DC components of the colour image directly in the spatial domain, followed by a saturation adjustment technique performed in RGB space.
Journal ArticleDOI
Aperture Jitter of Sampling System in AWGN and Fading Channels
TL;DR: It is demonstrated that the aperture jitter can influence the input signal of a sampling system but is independent of AWGN, and can be used in designing a wideband or radio-frequency-sampling digital communication system.
Journal ArticleDOI
Performance comparison of MRC and EGC on a MC-CDMA system with synchronization errors over fading channels
TL;DR: The comparison outcomes between MRC and EGC reveal that the MRC generally outperforms EGC in the uplink MC-CDMA system, however, EGC achieves better performance when the number of users is small, the normalized synchronization errors are low and the signal to noise ratio (SNR) is high.
