description: The given work is devoted to the possibility of obtaining optimal signal forms in the presence of restrictions on the peak-to-average power ratio (PAPR) of the emitted oscillations. The optimization technique for single-frequency signals hav-ing a predetermined decay rate of the out-of-band emission level is considered, if there is a limit on the PAPR of the emitted oscillations. Using this technique, it is possible to solve optimization problems for a wide class of spectrally efficient sig-nals. Various existing methods for reducing the peak factor of radiated oscillations are estimated. The main ideas and disadvantages of these methods were shown. A method for minimizing these disadvantages using optimal signals obtained in the course of solving the optimization problem is proposed. The technique of numerical and analytical solution of the optimization problem is proposed. The influence of restrictions on the solution of the optimization problem is shown, the influence on the PAPR is also considered for various values of the number of envelope decomposition coefficients and various values of the decay rate of out-of-band emissions. With the value of the parameter n = 2 and m = 60, the minimum value of the PAPR of the emitted oscillations equal to 3.06 dB was obtained. A simulation model of the formation and transmission of single-frequency signals with an estimate of the noise immunity of the reception is constructed. It was possible to synthesize signals with a gain of 4.2 dB compared with the case without restrictions. An experimental study was conducted on the basis of the HackRFOne SDR platform.
