摘要：
A TFI-OFDM transmission system includes a data generator generating data having a speed corresponding to a transmission speed mode; a convolutional encoder convolutional-encoding the data, an interleaver bit-interleaving the encoded data, an OFDM modulator inputting a first data group into a positive frequency domain and a second data group into a negative frequency domain, executing an IFFT, and outputting OFDM symbols; a buffer temporarily storing the OFDM symbols in order to sequentially transmit the OFDM symbols in a time domain at least two times; and a frequency generator generating certain frequencies to transmit the OFDM symbols in a certain number of frequency bands corresponding to transmission channels.
