( 5 ) from august , 2002 to april , 2003 , on the base of analyzing of 10kw valve tv transmitter of channel 14 , chongqing tv transmitting station , brought forward process the solidification scheme to 400w valve power amplifier of the driver 重庆大学硕士学位论文中文摘要( 5 ) 2002年8月至2003年4月期间，在对重庆电视发射台14频道( uhf ) 10kw电子管电视发射机进行研究分析的基础上，提出了对该机末前级400w电子管功率放大器进行固态化改造的方案并予以实施。
On the base of summarizing and reference to the achievement of uhf complete solid - state high - frequency power amplifier abroad , the author have made a deep research in uhf 10kw electron tube tv transmitter power amplifiers which are widely used inland , and asked for ideas of a lot of engineers of chongqing tv transmitting station , brought forward a practicable solidification scheme under the guidance of prof . gao chao and prof . guoyongcai , and made a successful practice at chongqing tv transmitting station 笔者在总结和借鉴国内外有关uhf全固态电视发射机高频线性功率放大器研究成果的基础上，对目前国内电视发射台普遍采用的uhf10kw电子管电视发射机高频线性功率放大器进行了深入研究，并广泛征求重庆电视发射台工程师的意见，在重庆大学高潮教授和郭永彩教授的指导下，提出了切实可行的固态化改造方案，并在重庆电视发射台实践成功。
This master ’ s degree thesis firstly introduces and discusses the principle of synchronization in sfn ( single frequency network ) based on dvb - t focusing on some key points , then presents a design of sfn time synchronization system based on fpgas , including the modules of sfn adapter after the mpeg - 2 re - multiplexer and sync system serving as the front - side of the dvb - t modulator at transmitters 本论文首先介绍并讨论了dvb - t单频网的时间同步原理,对其中的一些关键问题做了详细的分析,在此基础上提出了一种基于fpga的dvb - t单频网时间同步的硬件设计方案,即位于mpeg - 2系统层复用器之后的单频网适配器和发射台调制前端的同步系统的fpga设计。
