Synthesis Features of Optimal Signals Based on Eigenfunctions Considering the Limitations of Signal Parameters

In the work, studies, and analysis of the synthesis features of optimal signals based on eigenfunctions were carried out, taking into account the limitations on peak-to-average power ratio (P APR) and error rate of Faster-than-Nyquist (FTN) signal, considering the symbol rate during FTN transmission. In addition, the synthesis features of the pulses for high symbol rates were considered. As a result solutions were obtained for symbol rate up to 7/
$T$
without bit-error rate (BER) performance changes. Pulses had been obtained for 2/T and 3/T with P APR limitations without BER performance changes.
