基于海上安全信息数字广播系统的中波宽带/短波窄带接收模块设计

Design of Medium Wave Wideband/Short Wave Narrowband Receiving Module Based on Maritime Safety Information Digital Broadcasting System

结合ITU-R M.2058-0建议书中针对海上安全信息数字广播系统中扩展HF短波频段播发海上安全信息服务的应用需求,提出基于海上安全信息数字广播系统的中波宽带/短波窄带接收模块设计方法,详细论述了射频前端与基带设计的重点,给出了理论计算指标和实际验证接收测试的效果。经试验测试,其性能和功能指标均满足设计要求。

Combining with the application requirements of ITU-R M.2058-0 in the maritime safety information digital broadcasting system to extend the HF short wave frequency band to broadcast maritime safety information services,a medium wave broadband/short wave narrowband receiver module based on the maritime safety information digital broadcasting system is proposed.The design method,the key points of the radio frequency front-end and baseband design are discussed in detail,and the theoretical calculation indicators and the actual verification reception test results are given.After experimental tests,its performance and functional indicators meet the design requirements.
