Designing synchronization patterns minimizing the latency and the computational complexity for inaudible sound communication systems

抄録

The inaudible sound communication system of our implementation estimates the correct positions of received symbols in its decoding process by calculating the correlations with the pre-defined synchronization 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, compared with the conventional technique that employs random sequences for designing synchronization patterns.
