| Abstract: | In this paper, the principle of transmitter of DVB- T system and its realization is introduced firstly,and also give a more detail on transmitter of DVB - T. Then we explain the channel coding and COFDM modulation especially. At last, we give the implemention of hardware scheme based on FPGA platform is given, resolving the difficulty of channel coding and COFDM modulation especially and the detail realization on FPGA. |
