Заголовок статьи: Analysis of peak-to-average power ratio of N-OFDM signals
One of the significant drawbacks of OFDM and N-OFDM systems is high peak-to-average power ratio (PAPR). The use of N-OFDM signals gives an opportunity to reduce PAPR practically with the same methods that are applied to traditional OFDM. In this way, N-OFDM gives a considerable gain in spectral efficiency with a comparison to OFDM. In the article, the results of PAPR reduction of N-OFDM signals are presented. The implementation of phase response according to the analytical expression for the initial phase calculation of each subcarrier allows PAPR minimization an average of 12 dB for 155 subcarriers.
