Paper Abstract

In this article, we review our recent research progresses on the field programmable gate array (FPGA)-based real-time generation and reception of orthogonal frequency-division multiplexing (OFDM) signals for the short-reach direct-detection system and radio-over-fiber (RoF) system. With the low-complexity real-time digital signal processing (DSP) algorithms, a high-definition video signal with a data rate of 2.97 Gb/s transmission over 20 km single-mode fiber (SMF) without using forward error correction (FEC) technique is experimentally demonstrated in an intensity-modulated direct-detection optical OFDM system in the presence of sampling frequency offset (SFO). In addition, a real-time X-band OFDM-RoF system with heterodyne detection was also realized. With the help of Reed-Solomon coding with a multiplesymbol interleaving/de-interleaving scheme, the 16-ary quadrature amplitude modulation (16-QAM) OFDM-RoF signals over 10-m wireless and 2.26-km SMF-28 link was successfully achieved with a post-FEC bit error rate less than 1×10-9.
