A method for improving the energy efficiency of detection of optimal multifrequency SEFDM signals by introduction of quadrature components amplitude limitation is proposed. The results are obtained on the basis of simulation modeling. It is shown that it is possible to obtain an energy gain equal to 7 dB with a decrease of peak-to-average-power ratio by 8 dB. There is a optimal level of the peak-to-average-power ratio limitation, which, if exceeded, leads to a reduction in the energy gain.
