In this paper, a novel radio-over-fiber (ROF) scheme to simultaneously generate and transmit wideband code division multiple access (WCDMA) and millimeter-wave (MMW) signals by using a single dual-electrode Mach-Zehnder modulator (MZM) is proposed. There is no apparent nonlinearity induced by the ROF system. By employing this analog ROF signal transmission technique, the highly transparent fiber-wireless networks, which are ideal for multi-standard wireless system operation, can be realized.
