Abstract:

Filtered multitone modulation (FMT) technique has good ability on conquering multipath and interchannel interference (ICI). FMT is also affected from high peak-to-average power ratio (PAPR) just as OFDM, and the high PAPR has weakened the performance of FMT. The complementary cumulative distribution function (CCDF) of PAPR of FMT system is obtained based on the extreme theory. The CCDF analysis shows that the PAPR distribution of FMT is as same as that of OFDM, which has nothing to do with the filter type and length. Finally, the conclusions are verified by the simulation experiments.
