Digital Television Terrestrial Broadcasting Transmission System, The Originator Of The Fpga Design And Realization

The FPGA-based hardware implementation of the transmitter of GB20600-2006"Framing Structure, Channel Coding and Modulation for Digital Television Terrestrial Broadcasting System"has been completed in this project. The main hardware-platform is based on the Altra's Statix series FPGA chip EP1S80F1020C5. The realization of the energy dispersal, FEC-coding, constellation mapping, symbol interleaving, 3780-point IFFT OFDM, synchro-PN insertion, SRRC-FIR filter, etc have been implemented based on FPGA. The developing status of digital television, which is followed by the structure introduction of the transmitter of the GB20600-2006, is introduced firstly in this dissertation. And then the related knowledge about FPGA design is presented. The FPGA design of the modules of the transmitter is been importantly expatiated in chapter 3. In chapter 4, the amelioration of the system structure is been expatiated firstly. The simulation, analysis and validation of the whole transmitter of the GB20600-2006 is also been importantly expatiated in chapter 4. What I have mainly done in the project is listed as follows:1. Read papers associated with the project and get familiar with the basic principles of the GB20600-2006.2. Establish the FPGA design structure of the whole system and finish the interface definition of every sub-module.3. Ameliorate the FPGA designs of the 3780-point IFFT OFDM module and the SRRC-FIR filter module on FPGA.4. Complete the FPGA designs and validation the modules of the transmitter systerm of the GB20600-2006.5. Ameliorate the system structure of the transmitter.6. Finish the function simulation, analysis and validation of the whole system of the transmitter base on GB20600-2006.
