| Outline of Final Research Achievements |
Radio-over-Fiber(ROF) Transmission is a promising method for easer migration of broadband mobile communication systems. It employs very low-loss optical fibers that enable compact and simple front-end base stations. However, nonlinearity of Electro-Optical (E/O) conversion modulators distorts radio signals used in the new generation broadband wireless signals. Also, power distribution to the base stations is another issue to be solved. In this study, we proposed the front-end base station that employs Envelope Pulse Width Modulation (EPWM) transmitters and optical power feed. The performances of proposed technologies are validated by analysis and experiments.
