A universally optimum decoder for multiplicative audio watermarking

In this paper, we propose a novel detector for multiplicative watermarking. The decoder extracts the watermark data by comparing the variances of the watermarked signal and the original signal. Due to the use of the variance test, the decoder works independent of the distribution of the host signal....
