This paper puts forward the design method of dtv transposer using baseband demodulator as its core based on the analysis of its present status 摘要提出了以基带解调器为核心的数字电视转发器的设计方法。
In chapter 5 , the problem appeared in debugging has been analyzed . then the testing result of the modem has been given 第五章对调试过程中出现的问题做了分析,并给出了该调制、解扩解调器的一些测试结果。
All of the results indicate that the design requirements are met , and it is suitable for the application to pico - satellite communication 结果表明，解调器的整体性能达到了设计要求，适合在皮卫星通信中指令解调的应用。

But in fact , not all the demodulator can easily be designed and achieved , especially when the data transporting speed is quite low 但是在实际上并非所有的解调器都容易设计和实现，尤其是当传输的数据速率很低时，则很难。
The main purpose of this paper is to research and implement of the channel decoder ’ s hardware of sdtv set top box 本课题是基于st公司的标准清晰度数字电视信道解码器方案而实现的,采用了该公司的全数字单片qam解调器stv0297 。
