In this paper, Turbo Code is proposed in optical OFDM multimode fiber communication system in order to decrease the bit error rate (BER) of the system, which is mainly affected by the deep nulls of the magnitude response of multimode fiber in the high frequency region (above 3 dB). A simulation syst
## Abstract In this letter, we study the performance of lowβdensity parityβcheck (LDPC) codes in a Poisson optical channel with onβoff keying modulation. We modify the iterative decoding algorithm used in binary phaseβshift keying modulation and additive white Gaussian noise channels. The simulatio
