摘　　要：We propose and experimentally demonstrate the heterodyne mixing and polarization diversity techniques in radio over fiber （ROF） systems with the advantages of high sensitivity and dispersion endurance. The generation of 2.5 Gb/s optical DPSK and PSK signals, fiber propagation and wireless transmission over 15 GHz subcarrier are illustrated with very low sensitivity of -26 and -32 dBm, respectively. Moreover, based on the wireless polarization diversity techniques, we successfully performed the transmission of 1.3 Gb/s uncompressed high definition television （HDTV） signals with high quality.We propose and experimentally demonstrate the heterodyne mixing and polarization diversity techniques in radio over fiber （ROF） systems with the advantages of high sensitivity and dispersion endurance.
