papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.
