短距离声通信研究及实现

Short Range Acoustic Communication Research and Implementation

随着电子技术的发展,对短距离无线通信技术的需求及应用越来越广泛,通信频率共存导致的通信干扰会越来越严重。同时,强电磁环境中短距离无线通信也会受到严重干扰甚至无法进行。提出并验证了一种可应用于这类环境中的短距离声通信方式。在这种短距离声通信中,信号被调制到声波上,通过声波在空气中的传播来实现数据通信,因此它不占用无线信道带宽、不受电磁干扰影响。

With the development of electronic technology,the needs and application of short-range wireless communications technology become more and more widely,communication interference caused by frequency coexistence will become increasingly serious.And short-range wireless communications will be severely disrupted or even impossible in strong electromagnetic environment.A short-range acoustic communication which can be applied in these environments was proposed and demon strated.In the short-range acoustic communication,signals are modulated to the sound waves,and data communication achieved through the propagation of sound waves in air.Therefore,it does not occupy the wireless channel bandwidth and interference from electromagnetic.
