Audio Watermarking Based on BCH Coding Using CT and DWT

A blind Cepstrum transform-Discrete wavelet transform (CT-DWT) composite audio watermarking based on BCHcoding 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.
