本文介绍了一个DAB(Digital Audio Broadcasting)原型发射机数字基带部分的设计与实现
包括复接器、信道编码器和OFDM调制器.它的内部功能和外部特性完全符合ETS 300 401和其他相关标准
支持多种业务类型
具有方便的用户接口.它的I/O接口和核心部件采用基于通用内部接口的模块化设计
可根据用户需要灵活配置.同现有的发射机产品相比
具有成本低
易于调试
可灵活配置等特点.
The design and implementation of the digital baseband part of a DAB transmitter prototype are introduced.It is composed of ensemble multiplexer
channel encoder and OFDM modulator.The equipment is totally compatible with ETS 300 401 and other related standards.It supports services with various data formats and supplies a convenient user interface with the ensemble multiplexer as well.All of its I/Os and the core parts are implemented using modular design based on universal internal interface
thus can be flexibly configured according to different demand.Compared with the existing products
it can provide higher flexibility and operating easiness on a much lower cost level.
