The clipping is one of the simplest distortion based techniques to reduce the PAPR of the
OFDM signal.
The Dual polarization optical
OFDM system is suggested and it's performance is checked with different values of effective area (60-150 [micro]m2) and different percentage of cyclic prefix (25%,12.5%,6.25%,3.125% ,1.56%,0.78%, 0.39%); and the best value of bit error rate is examined.
The main idea of PTS method is to partition the main
OFDM sequence into many sub-sequences, and then each sub-sequence is multiplied with a different weights until the optimum value with lowest PAPR is achieved.

Recently, attention is given to the use of machine learning to detect, estimate, and suppress impulsive noise present in an orthogonal frequency division multiplexing (
OFDM) systems.
The OCT precoding scheme is useless in PAPR reduction, where the PAPR is almost the same as the traditional
OFDM scheme without precoding.
From (17), it can be noted that there is no coupling between the distance and angle parameter estimation for
OFDM array radar echo signal under the condition of narrow-band signal, and therefore, the joint estimation on the range and DOA can be carried out.
At the receiver, the I/Q modulated optical
OFDM signal is directly detected by delay line interferometer with balanced detection.
