Abstract


In recent years, the digital trunking communication system has been widely used in enterprises , mining , oil field , farm , public security and armed forces and other departments , the digital trunking system has been rapid development . The DMR protocol proposed by the European Telecommunications Standards Institute (ETSI) as a new type of digital trunking communication protocol has broad prospects for development . This paper reviews the development of the digital trunking communication system , the DMR protocol , in particular, the forward part of the DMR protocol to do a brief introduction , and designed and implemented the DMR agreement repeater station baseband hardware modules . Analyzed the design of the repeater station , the first process on the function and operation of the repeater station , to improve system capacity , the repeater station is designed as a dual - channel structure ; primarily on the connection between the chip in circuit design , a specific description . Debugging of hardware modules , mainly debugging methods and processes , to do the analysis results of the commissioning . After debugging, the baseband hardware module can achieve the DMR protocol requirements repeater stations .
