摘要

最近，我们提出了一种基于m序列码的扩频技术的超声波多址方法。但是，其效果取决于预设的阈值水平。在本文中，我们考虑了一种新的定量估计方法，利用两个传声器之间的归一化互相关函数。利用这种定量估计方法，研究了预设水平的影响，并给出了预设阈值的最优值。

P2D-2 Quantitative Estimation of Ultrasonic Multiple Access Method Based on M-Sequence Code

Recently, we have proposed an ultrasonic multiple access method based on the spectrum spread technology using M-sequence codes. However, its effect depends on the preset threshold level. In this paper, we consider a novel quantitative estimation method using the normalized cross-correlation function between two microphones. Using this quantitative estimation method, we investigate the effect of the preset level and show the optimal value of the preset threshold.
