Abstract

Constellation modification method for OFDM peak power reduction is considered. Choosing function which sum with OFDM symbol gives new symbol with lower peak power is the main idea of method. Signal modification by means of this function carrying out at subcarriers modulation constellation domain. Fourier transform of given function is executing, values obtained for the spectral components are added to the spectral components of the signal and reformed modified OFDM symbol. Main qualities and capabilities for given modification function and different subcarrier modulation methods is analyzed. Obtained plots of peak factor of the coefficients of the algorithm and the algorithm efficiency.
