A radio-over-fiber (ROF) system that combines a wireless linkand an optical fiber link is studied. After introducing the configuration and analyzing the nonlinear distortion of the system, the Volterra series is proposed and used to model the system. The adaptive least mean square (LMS) and recursive least squares (RLS) algorithms for identifying the Volterra kernel are studied. A simulation is given, which uses both Volterra LMS and Volterra RLS to model a nonlinear ROF system, and indicates that the method is efficient.
