Acoustic data transmission by extension on the time domain approach

The main goal of acoustic data transmission is to deliver data by overcoming acoustic channel distortion. This paper presents a data transmission method that modifies the amplitude of the time domain audio signal imperceptibly. The main advantage of the proposed method is that the synchronization process can be conducted simultaneously while data is being extracted at the receiver side. The evaluation results show that the proposed method successfully overcomes indoor acoustic channel distortion and delivers data.
