摘要
在阐述宽带数字电视地面广播 ( BDB-T)中符号同步基本原理的基础上 ,提出了一种新的符号同步控制方案并设计出相应的 FPGA ( Field Programmable Gate Array)硬件电路 ,通过在实际无线环境中的传输测试 ,证明该方案在数字电视地面广播系统中 ,能合理正确地校正控制结构 ,易于实现且性能优良。
A new symbol synchronization control scheme and its corresponding FPGA(Field Programmable Gate Array) hardware circuit is proposed on the basis of the fundamental theory about symbol synchronization technique in broad-band broadcasting terrestrial system.Through the transmission testing in the actual wireless environment, it proves that the proposed scheme can rectify the control structure reasonably and can easily be implemented with excellent performance in BDB-T(Broad-band Digital Broadcasting-Terrestrial) system.
