Standard spread spectrum audio watermarking algorithms offer BER unacceptable for reliable transmission of data. Causes of unreliable watermark detection are often attacks that distort the watermarked audio in fading-like manner, disabling the correlation-based detectors to extract data. In this paper, consideration of capacity of the audio watermark channel in the presence of fading-like distortion is performed. It is shown that turbo codes offer convenient trade-off between capacity of the… CONTINUE READING
