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

basic_ofdm_inter
basic ofdm with interlever:
The
transmitter section converts digital data to be transmitted, into a mapping of
subcarrier amplitude and phase. It then transforms this spectral representation of
the data into the time domain using an Inverse Discrete Fourier Transform
(IDFT).
The Inverse Fast Fourier Transform (IFFT) performs the same operations as an
IDFT, except that it is much more computational efficiency, and there is used in
all practical systems. In order to transmit the OFDM signal the calculated time
domain signal is then mixed up to the required frequency.

Recursive_integer_division
递归法求解整数划分。
整数划分,是指把一个正整数n写成如下形式:
n=m1+m2+…+mi (其中mi为正整数,并且1 <= mi <= n),则{m1,m2,...,mi}为n的一个划分。
如果{m1,m2,...,mi}中的最大值不超过m,即max(m1,m2,...,mi)<=m,则称它属于n的一个m划分。这里我们记n的m划分的个数为f(n,m) (Recursive method integer division. Integer division, refers to a positive integer n written as follows: n = m1+m2+ ...+mi (where mi is a positive integer, and 1 < = mi < = n), then {m1, m2, ..., mi} is a division of n. If {m1, m2, ..., mi} does not exceed the maximum value of m, i.e., max (m1, m2, ..., mi) < = m, m n is said that it belongs to a division. Where m is the number of division n our mind is f (n, m) )
