Robust Estimation of Amplitude Modification for Scalar Costa Scheme Based Audio Watermark Detection the received signal itself for estimation of the quantization step size. The optimal searching interval is determined to satisfy both detection performance and computational complexity. Experimental results show that the proposed algorithm can estimate the modified quantization step size accurately
