Digital audio watermarking based on holographic nonlinear limiter

A new approach of digital audio watermarking by use of nonlinear amplitude limiting computer-generated hologram (CGH) is proposed to significantly improve the robustness than traditional CGH method. The amplitude and phase are extracted on the basis of traditional Fourier transform holography. Binar...
