orthogonal frequency division multiplexing (OFDM) is emerging as the leading technology for high data rates. The OFDM based on multicarrier transmission that transforms a wideband channel into a group of thin-band channels. The high peak to average power ratio (PAPR) considers the main drawback factor in this system, so the companding technique modifies the amplitude of OFDM signal to reduce this factor. The proposed A-law companding technique has been implemented in intensity modulation/direct detection optical orthogonal frequency division multiplexing (IM/DDOOFDM). The proposed companding scheme guarantees the improved performance in terms of bit error rate (BER) and quality factor (QF) while reducing PAPR effectively and efficiently by modifying the amplitude of the transmitted signals. Our results confirm that the suggested scheme exhibits a good ability to reduce PAPR and a good BER performance based on the use the A factor. At the complementary cumulative distribution function (CCDF) of 10- 3, the PAPR value of our proposed scheme is about 4.4 dB lower than those of un-companded signal at best control factor used of A at 87.6, accordingly the QF is 2.5 dB and the BER is 6.2×10-3 at a distance 900km without any equalization technique or training sequence or any channel estimation.
