OFDM based DVB-T system implementation using MATLAB and HDL coder

摘要

Digital Video Broadcast-Terrestrial (DVB-T) is a most extensively use standard for terrestrial TV transmission in the world. The OFDM has advantages of high spectral efficiency and inherent robustness against channel fading so it is used in DVB-T system. The BER performance of the DVB-T in 2K mode for 4-QAM constellations under AWGN, Rayleigh and Rician channel models is analyzed. In this research work, DVB-T system is implemented first using MATLAB and then the MATLAB code is converted into VHDL code using HDL coder according to European telecommunications standards institute (ETSI), EN 300 744 standard. Synthesis and Simulation of OFDM based DVB-T in 2K mode have been carried out using Xilinx tool.
