一种采用DAB技术的分区广播接收终端设计

摘要

According to the digital audio broadcasting(DAB(technology,this paper designed a new wireless regional radio receiver terminal.Such novel partition broadcast receiving terminal,using a proactive identification mechanism,not only can filter and shield the specified broadcast information,but also can accurately judge the legitimacy of the transmission source of the broadcast information.Test results showed that the partition radio receiving terminal can correct completion of the partition broadcast each function,reaction time below 10s,signal sensitivity to-99dBm.%　　本文采用数字音频广播(DAB)技术，设计了一种新的无线分区广播接收终端，制定了一套主动身份识别机制，不但能筛选和屏蔽指定的广播信息，还能进行判断广播信息发射源的合法性.经测试，这种分区广播接收终端能够正确的完成分区广播的各项功能，反应时间在3s以内，信号灵敏度达到-99dBm.
