Simulating CDF of Peak to Average Power Ratio for OFDM

Obtain the CDF plots of PAPR from an OFDM BPSK transmission specified per IEEE 802.11a specification

Description

Per the IEEE 802.11a specifications, we 52 have used subcarriers. Given so, the theoretical maximum expected PAPR is 52 (around 17dB). However, thanks to the scrambler, all the subcarriers in an OFDM symbol being equally modulated is unlikely.

Using a small script, the cumulative distribution of PAPR from each OFDM symbol, modulated by a random BPSK signal is obtained.
