UWB communication TFI-OFDM for (Time Frequency Interleaved Orthogonal Frequency Division Multiplexing) transmission system, and a data generation unit for generating data having a speed corresponding to the transmission rate mode, Kern beolru the data as a data group of a predetermined number a convolutional encoder for relational encoding, and an OFDM modulator for each of said data group output to IFFT modulated OFDM symbols, time to the OFDM symbol to transmit is repeated at least twice for the OFDM symbol in order in the time domain It has parts in a predetermined frequency band corresponding to the buffer and the transmission channel for storing a frequency generator for generating a predetermined frequency in order to transmit the OFDM symbol. UWB, TFI-OFDM, a time domain extension, tone interleaving, convolutional encoder
