基于云端软件定义水声的跨域通信系统
Cross-Domain Communication System with Cloud-Based Software-Defined Acoustic
摘要
Abstract
Due to the restriction of acoustic communication performance,the performance of data transmission across the water-air interface is difficult to further improve.In this paper,a cross-domain communication system architecture with cloud-based software-defined acoustic(C-SDA)was proposed.C-SDA moved the underwater acoustic receiver from the surface relay to the cloud(i.e.,the monitoring center)and used the radio communication bandwidth to exchange the computing resources of the cloud to demodulate and decode the acoustic signal.In this case,the acoustic-radio dual-stack protocol of the relay gateway was simplified to a single-stack structure,which avoided packet capsulation and re-capsulation and saved hardware costs.The C-SDA not only enabled advanced communication signal processing but also promoted rapid updates and iteration of acoustic communication technology.The field test results show that C-SDA can be applied to equalizers with higher performance and achieve a significant improvement in bit error rate compared with the self-developed embedded underwater acoustic receiver.关键词
