Optimal Parameter Estimation of the ML Test Based Audio Watermark Decoder  

Lee, Jin-Geol (배재대학교 전자공학과)
Abstract
Based on the fact that audio signals in the time domain have the generalized Gaussian distribution. an optimal parameter estimation of the ML (maximum likelihood) test based audio watermark decoder. which leads to the minimal bit error rate, is Proposed. Its superiority of performance over the existing estimation and the conventional correlation based decoder is demonstrated experimentally.
