We have demonstrated a novel 22 Gbit/s 64 QAM scheme to generate orthogonal frequency division multiplexing (OFDM) signals for radio over fiber (ROF) systems using cost-effective optical filter fiber Bragg grating (FBG). We employ the FBG because the repetitive frequency of the RF source and the bandwidth of the optical modulator are largely reduced and the architecture of the ROF system is simpler...
The performance of theory analysis on DD-OFDM system for ROF links has been investigated. The theoretical model of DD Optical OFDM transmission system has been discussed. It consists of fundamentals and mathematical analysis of a typical DD-OFDM system. A typical low-cost DD-OFDM system has been simulated. The results show that the simple structure and low-cost of the DD-OFDM system is attractive...
