Designing Synchronization Pat- terns Minimizing the Latency and the Computational Com- plexity for Inaudible Sound Com- munication Systems

The inaudible sound communication system of our imple-mentation estimates the correct positions of received symbols in its de-co ding process by calculating the correlations with the pre-defined syn-chronization patterns. This paper describes that a theoretical approach based on solving Euler graphs taking account of constraint conditions may potentially provide more efficient synchronization patterns, com-pared with the conventional technique that employs random sequences for designing synchronization patterns.
