摘要： PURPOSE: A TFI-OFDM transmission/reception system for an ultra wide band communication to mitigate the interference between piconets and a method for transmitting/receiving of the same are provided to mitigate the collision due to the adjacent SOP in the piconet channel environment by transmitting the modulated OFDM symbols at least more than two times. CONSTITUTION: A TFI-OFDM transmission/reception system for an ultra wide band communication to mitigate the interference between piconets includes a data generating unit, a convolutional encoder(321), an interleaver(331), an OFDM modulation unit(351), a buffer(381) and a frequency generation unit(391). The data generating unit generates the data having the speed corresponding to the transmission speed mode. The convolutional encoder performs the convolution encode for the data. The interleaver performs the bit interleaving for the encoded data. The OFDM modulation unit inputs the first data group to the positive frequency region and inputs the second data group to the negative frequency region. The OFDM modulation unit performs the invert fast Fourier transformation(IFFT) to output the IFFT modulated data as an OFDM symbol. The buffer temporally stores the OFDM symbol to transmit the OFDM symbol to the time region at least two times sequentially. And, the frequency generation unit generates the predetermined frequency to transmit the OFDM symbol to the predetermined frequency bandwidth.
