Orthogonal Frequency Division Multiplexing is one of the most
important multiple carrier modulation format, which has many applications in
wireless communication and optical communication. It is considered as an
excellent method for fast optical communication inferable from its high spectral
efficiency and its strength to path losses. Peak to average power ratio is
regarded as one of the main problems that are experienced by the optical
orthogonal frequency division multiplexing system, which directly affects the
characteristics of the system. The current paper proposes an efficient technique
to reduce Peak to Average Power Ratio by the modified Dursun’s method or the
so called modified discrete sliding norm transformer in coherent optical
orthogonal frequency division multiplexing system for the first time to the base
of our knowledge consequently. The proposed technique does not need to send
side information to the receiver; also, it does not degrade bandwidth. This
algorithm lessens Peak to Average Power Ratio in the optical coherent
Orthogonal Frequency Division Multiplexing system to about 4.15 dB at
complementary cumulative distribution function (CCDF) probability of 10-3 and
improves the system performance.
