Abstract :
Digital predistortion for directly modulated RoF links is experimentally investigated. A memory-polynomial-based predistorter model is directly identified from measurements of the baseband OFDM input-output signals and using the least-squares method in Matlab. The RoF link nonlinearity has been reduced implementing this technique.
