Abstract

Record 35-Gb/s wireless signal transmission is experimentally demonstrated using a Radio-over-Fiber system employing the single-carrier modulation format and 32-quadrature amplitude modulation (QAM). The total occupied spectrum of the transmitted 60 GHz signal was 7-GHz, representing a spectral efficiency of 5 b/s/Hz. A decision feedback equalizer (DFE) was utilized to compensate for the signal distortion caused by fiber dispersion and self-inter-symbol interference. After transmission over 25-km single-mode fiber and 3 m wireless distance, the power penalty was less than 1dB.
