Abstract :
A perfect approximation of the peak-to-average envelope power ratio (PAR) distribution for the continuous-time OFDM baseband signals, in which not all the subcarriers are used as specified in many international standards, is derived. Analysis result shows that the PAR distribution depends on the number of the actual used subcarriers, not on the number of the IFFT points
