摘要
介绍一种符合我国GB20600—2006标准的地面数字电视广播激励器的设计方案,本方案采用FPGA实现激励器的核心功能,包括GB20600—2006信道编码和调制方式、单频网适配、MPEG传输流输入输出管理和非线性数字预校正;采用二次变频技术实现了全频段的上变频;采用ARMCPU和嵌入式Linux操作系统实现整机控制。
This paper introduces a design of the GB 20600 - 2006 Digital TV Exciter. The design adopts FPGA to implement the core functionalities, including the GB 20600 -2006 channel encode and modulation modes, SFN adoption, MPEG TS management and non-linear pre-correction; it also employs two-time frequency inversion technology to implement the frequency upconverter and uses ARM CPU and Embedded Linux to control the whole equipment.
