where N is the number of subcarriers and z is the threshold. Basically,
this probability function is used as a graph to determine the ability
of an algorithm in reducing the PAPR of the OFDM signal and the
PAPR is usually compared to an unmodified OFDM signal at 0.01%
CCDF, which is shown by the 10
–4
CCDF in the horizontal vec-
tor of graphs. A typical OFDM signal without any PAPR reduction
technique has about 8 dB to 13 dB PAPR at 10
–4
CCDF (Raab etal.,
2002). erefore, when a PAPR reduction technique is applied to the
OFDM system, it is expected to reduce the 13 dB PAPR to some
lower value. Acco ...
