The clipping is one of the simplest distortion based techniques to reduce the PAPR of the OFDM
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
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.
