Abstract :
An optical Orthogonal Frequency Division Multiplexing (OFDM) has been proposed based on Wavelet packet transform (WF-O-FDM). In this paper, a performance investigation has been made to check the validity of the proposed work. This investigation has been made based on two crucial factors, BER and the Complementary Cumulative Distribution Function (CCDF). A MATLAB based simulation has been taking over to examine this performance and to compare it with conventional OFDM that is based on FFT. The extracted results show that the WF-O-FDM depicts an improvement of the BER for the same optical bandwidth occupancy, while the Peak to Average Power Ratio (PAPR) values has been reduced for about 85% compared with the conventional one.
