Acoustic data transmission based on complex quadrature mirror filterbank transform
Seungkwon Beack, Taejin Park, Kyeongok Kang · 2014
Acoustic data transmission is a technique used to imperceptibly deliver data on sound waves. This paper presents a new approach to embed the data in a complex quadrature mirror filterbank by adopting phase shift keying modulation. The evaluation results show that the proposed method successfully delivers the data overcoming severe acoustic channel distortion with a low bit error rate.
