Performance Investigation in Optical OFDM

Abstract

Optical Orthogonal frequency division multiplexing (OOFDM) has been one of emergent and competent technique to be used with future generation communication networks, due to less inter symbol interference caused by a dispersive channel. In view of it this paper presents investigated transmission performance with novel designed OOFDM system for different transmission parameters with fixed communication length. To achieve good transmission performance in optical OFDM system it must be optimized in various ways. Higher bit rate transmission is favored with low baud rate, BPSK modulation scheme, booster power in the range of zero to 14dB constellation patterns are very good. Further it is also noticed that transmission is affected with variation of cyclic prefix and QAM size and number of subcarriers.
