Abstract :
Optical and electrical linearization techniques are reviewed for broadband radio over fiber transmission. The optical linearization includes optical mixed polarization and two-wavelength linearization, and the electrical linearization includes analog pre-distortion circuit. The optical linearization leads to more than 10-dB improvement of spur-free dynamic range (SFDR). The analog pre-distortion circuit that is simple and of low-cost results in about 10 dB improvement of SFDR.
