This article proposes a mathematical expression for
the calculation of the bit error rate (BER) in a filtered multitone modulation scheme (FMT) when the transmission is carried out through a stationary multipath fading channel, assuming a perfect knowledge of that channel. The results of the simulations show that the expression presented here is very similar to the performance curves obtained by Monte Carlo simulation, especially when the number of tones is large enough to guarantee a flat behavior of the channel on each tone. The expression applies
to any order M of the M-QAM modulation used on each tone.
