摘要

提出了一种基于BCH编码的盲倒频谱变换-离散小波变换(CT-DWT)复合音频水印算法。它利用了纠错编码和倒频谱变换的优点来降低提取水印的误码率。实验结果表明，该方案嵌入的水印具有鲁棒性和不可见性。此外，bch编码方案的性能优于非bch编码方案。

Audio Watermarking Based on BCH Coding Using CT and DWT

A blind cepstrum transform-discrete wavelet transform (CT-DWT) composite audio watermarking based on BCH coding is proposed. It takes the advantages of error correcting coding and cepstrum transform to lower the bit error rate (BER) of the extracted watermark. Experimental results show that the watermark embedded with our proposed watermarking scheme is robust and invisible. Moreover the performance of the BCH-coding scheme is superior to non BCH-coding scheme.
