Abstract: An algorithm that can minimize the effects of a tone interference in a Fourier transform data transmission (FTDT) system is derived. The algorithm works well even in the presence of additive white Gaussian noise. The error performance of the FTDT system with this tone removal method is discussed. A simulation study shows that this algorithm limits the system error performance deterioration due to a large tone interference to about 0.3 dB. The implementation of this algorithm requires three complex words at the transmitter transform input to be filled with zeros. The observed values at the corresponding location at the receiver transform output are used to evaluate the characteristics of the interfering tone. The effects of the tone interference can then be eliminated.
