In this paper, we propose a novel and simple method to generate millimeter-wave vector signals using only one phase modulator (PM) and phase-precoding technique, in which the precoded microwave vector signal is used for the drive of the single PM. We experimentally demonstrate that this concept of the generation of quadrature-phase-shift-keying-modulated vector signal can be employed in our radio-over-fiber (RoF) system architecture based on our proposed scheme. By this scheme, we simplify the configuration and reduce the cost of the RoF system.
