The Originator Of The Dvb-t Channel Model Implemented In Hardware

With the broadcasting television transformating from analog to digit technolgoy, it is critical to develop the digit technology, especially digit television broadcasting system. Currently, the terrestial digit television broadcasting protocal of our country is under developed.The charactristics of radio transimission is the first question you need to consider when designing any mobile communication system.In order to guarantee the quality of the mobile communication system, you must have a extensive understanding about the mobile transimission environment and find appropriate ways to offset the impact of interference and shading in channel transimission.Therefore, we need to setup the channel modeling, in that we can design and test the mobile communication system in laboratory environment.This project is to design digit television terretial broadcasting modulation and channel modeling.At first, this article talks about the DVB-T transmission system based on DVB-T protocol and its hardware architecture.Then it introduces the modeling method of frequency selection channel in mobile transmission environment. It also gives the model hardware implementation architecture and simulation results.Based on these outcomes, we can see that the function and performance of channel models both satisfies the design requirement.
