Then  the high speed OFDM technology receives increasing attentions in mobile communication. Modulation programs are designed with VHDL based on the principle of OFDM in the paper. First  from the results of VHDL simulation  after OFDM fundamental is introduced  the realization of baseband operations  such as interleaver  subcarrier modulation  IFFT and adding CP  are presented. Finally  implemented programs are validated on the actual implement system. Experimental results indicate that setup time corresponding to transmission velocity is only 71.05s and steady time is approximately 6 times as setup time  that is  not only achieving the high speed transmission  but also supplying adequate modulation time. 2010 IEEE.
