In this paper, an efficient implementation of high throughput Digital Video Broadcasting (DVB) system based on the Orthogonal Frequency Division Multiplexing (OFDM) modulation for terrestrial links is proposed. The proposed architecture uses an improved optimization methods to obtain high speed system. To verify the efficiency of this system a DVB-T simulator in MATLAB matched with European Telecommunications Standards Institute (ETSI) is used to investigate the hardware design performance. The joint simulation of Xilinx ISE and MATLAB was performed including information framing, channel coding, and modulation. Also, a systematic design procedure based on FPGA for the proposed DVB-T system is presented and the results are reported. Hardware implementation results demonstrate the effectiveness of the proposed system and show that there is a good match between fixed-point implementations and floating-point simulations, while the high-throughput architecture is achieved in hardware implementation using the speed optimization methods in the design.
