Abstract
OFDM technology is being promoted as one of significant ingredient in the development of the 4G
communication technology that will be commercialized in forthcoming decade. This paper presents
proposed topology to perform performance study of optical OFDM system with different modulations.
Simulated results report that performance of optical OFDM transmission is dependent upon a number
parameters selected as baud rate of transmission, cyclic prefix , QAM size and FFT size is selected by
analyzing the transmission channel by the use of OFDM training symbols. Further OOFDM transmission
performance under AWGN channel the MSK scheme and under Rayleigh channel environment BPSK
scheme employing OOFDM has depicted good optical transmission performance. It has been perceived
that better transmission performance is dependent upon best fit selection of number of optical OFDM
transmission parameters
