An Audio Watermarking Technique Using BPSK with Variable Carrier Frequency

가변 반송파 BPSK를 이용한 오디오 워터마킹 기법

In this paper, we consider the problem of digital audio watermarking to robust about compression without original audio data. We specifically address the audio watermarking using BPSK with variable carrier frequency. This technique make audio data embeded watermarking robust with compression attack, for example MPEG, AC-3, etc.
