【摘要】 船舶数据交换量的增加导致现有的船用自动识别系统(AIS) 87B/88B VHF通信信道堵塞严重,数据的完整性传输受到现实的考验。为解决严峻的通信信道压力,甚高频数据交换系统(VDES)应运而生。文章基于软件无线电(SDR)技术,搭建基于Gnuradio软件及2块HackRF One硬件的软件无线电开发平台,进行16位正交幅度调制解调(16QAM),实现信号收发与处理,为船用VDES地面系统研究提出了一种可行性方案。更多还原

【Abstract】 As a result,the existing marine automatic identification system( AIS) 87 B/88 B VHF communication channel is blocked seriously,The integrity of data transmission is tested by reality. To deal with severe channel pressure,VHF data exchange system( VDES) came into being. Based on software radio( SDR) technology,Set up software radio development platform based on Gnuradio software and 2 HackRF One hardware,16-bit orthogonal amplitude modulation and demodulation( 16 QAM),conducted to receive and process signals,a feasible scheme is proposed for marine VDES ground system research.更多还原
