The Effectiveness of Application of Multi-frequency Signals Under Conditions of Amplitude Limitation

Simulation modeling of information transmission using spectrally efficient multi-frequency signals with an amplifier and a limiter on transmission was held. The possibility of increasing the average radiation power while limiting the peak-to-average power ratio (PAPR) is shown. However, with a more significant limitation on the PAPR, a greater interference between signals from adjacent subcarriers begins to appear. Thus, it is possible to search for an effective value for PAPR limiting. In this paper, cases of multi-frequency signals are considered with a different value of the frequency separation between subcarriers, and the case of the simultaneous use of a smoothed shape of envelopes is affected.
