A major concern in the use of optical-OFDM systems is their limited dynamic range due to nonlinear distortion (NLD) and high peak to average power ratio (PAPR). In this paper, an adaptive filter-based compensation scheme is proposed for a coded direct detected-optical-OFDM system. Moreover, different turbo code rates (DTCRs) are applied for the subcarriers of different regions. For subcarriers in low and high frequency regions a lower rate turbo codes are used. On the other hand for remaining subcarriers a higher rate turbo codes are preferred. This kind of system helps to provide high receiver sensitivity and improved Bit error rate (BER) by more than 2dB.
