摘    要:针对现有岸船短波通信系统存在的数据传输速率低、多业务支持能力弱等问题,提出了一种宽带岸船短波通信系统。在应用数字调制技术和正交频分复用(OFDM)技术后,系统接收机灵敏度由-74 dBW降到了-91 dBW,数据传输率由9 kbit/s提升为50 kbit/s。对宽带岸船短波通信系统与其他岸船通信系统的多网融合潜力进行了分析,为新一代岸船通信网的建立提供了思路。

关 键 词:航天测量船  岸船通信  宽带短波通信  正交频分复用  多网融合

Abstract:For the problem that the data rate and multi-service support ability of the existing ship-shore communication system is low and weak,this paper presents a wideband High Frequency(HF) ship shore communication system.With the application of digital modulation and Orthogonal Frequency Division Multiplexing(OFDM) technology,the sensitivity of the system receiver is reduced from -74 dBW to -91 dBW,the data transmission rate is increased from 9 kbit/s to 50 kbit/s.The multi-network merging potential of wideband HF communication system with other shore-ship communication systems is analyzed,which provides a way for establishing the new generation of ship-shore communication network.
Keywords:space tracking ship  ship-shore communication  wideband HF communication  OFDM  multi-network merging
