摘　　要：为了降低信号在传输过程中的损耗,提出一种数字电视信号高效率传输技术。分析数字电视信号结构,设计数字电视信号高效率传输信道,在此过程中,需要将信号特性与传输信道参数进行对接,以此调整传输信道的频数,实现对信号传输行为的约束。同时,引进数字微波技术,采用划分信号层数的方式,降低信号的噪声,通过此种方式,确定噪声最优分解度。根据基带调控中的信号编码形式,对传输的数字电视信号进行实时追踪,以此达到对信号高效率传输的目的。将设计的技术应用到实例,证明此项技术在实际应用中,可以降低信号传输的损耗,满足信号高效率传输需求。In order to reduce the signal loss during transmission,a high-efficiency transmission technology for digital TV signals is proposed.Analyze the structure of digital TV signals and design high-efficiency transmission channels for digital TV signals.In this process,it is necessary to connect signal characteristics with transmission channel parameters to adjust the frequency of transmission channels to achieve constraints on signal transmission behavior.At the same time,digital microwave technology is introduced to reduce the noise of the signal by dividing the number of signal layers,and in this way,the optimal resolution of noise is determined.According to the signal encoding form in the baseband control,real-time tracking of the transmitted digital TV signal is carried out to achieve the purpose of high-efficiency transmission of the signal.Applying the designed technology to an example proves that this technology can reduce the loss of signal transmission and meet the demand for high-efficiency signal transmission in practical applications.
