In this paper, we present a robust watermarking method against geometric distortions and several attacks of signal processing. In the proposed watermarking method, image normalization is used to get geometric invariant feature and watermark embedding and detection are carried out in the Discrete Cosine Transform (DCT) domain. Texture based image block classification in DCT domain is also used to get...
In this paper, we propose and analyze a novel multicarrier (MC) multicode (MCD) code-division multiple-access (CDMA) system employing wavelet packets (WPs) for modulation. This system can achieve robust performance against multipath fading due to the localization of WPs in the time and frequency domains. The analytical framework is presented, and the system performance with diversity is evaluated...
