综述了宽带无线电光纤传输中的光线性化和电线性化技术。光线性化包括光混合偏振和双波长线性化，电线性化包括模拟预失真电路。光学线性化使无杂散动态范围（SFDR）提高了10 dB以上。该模拟预失真电路结构简单，成本低，SFDR提高了约10 dB。
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.
