Improved Performance Investigations on OFDM-RoF Transmission Links Using ODSB and OSSB Modulation Techniques

Abstract

AbstractIn this work, simulative investigation to evaluate the performance of OFDM-RoF transmission links using ODSB and OSSB modulation schemes at high transmission rate is reported. Further, the results have been reported by compensating the degradations introduced by fiber dispersion using DC fiber for the proposed SSB-OFDM-RoF transmission links and a comparison is presented for evaluating the performance of such systems with and without DC fiber. Our result shows that the OSSB performs better than ODSB modulation scheme as the later severely suffered with fading problems due to fiber dispersion. In case of OSSB with DC fiber dispersion compensation technique, an improvement in SNR ratio and total power received is achieved in comparison to OSSB without DC fiber.
