On the Estimation of Distortions of Optimal Spectrally Efficient Signals with a Decrease in the Accuracy of the Expansion Coefficients and a Restriction on the BER Performance

The paper presents a method for optimizing single-frequency signals with a given rate of decrease in the level of the energy spectrum and restrictions on the correlation coefficient. The influence of the restriction on the choice of the number of expansion coefficients in the Fourier series and the value of the PAPR of radiated oscillations on the solution of the optimization problem is considered. The energy loss with a decrease in the number of expansion coefficients of the optimal envelope from m = 21 to m = 2 is 0.1-0.2 dB with an error probability of 10-3.
