More than a brief introduction to the linear technology in the field of wireless communications and radio and television within the wide application of linearization techniques to achieve a certain degree of difficulty, but the benefits of the system is to improve efficiency and save the volume and reduce costs. For each type of system characteristics and requirements of appropriate technology should be used. Such as CDMA single carrier frequency can be used simple linear pre-distortion techniques to achieve, and WCDMA high-power multi-carrier linear should use digital pre-distortion feed-forward or other complex technologies. Digital pre-distortion technology has begun to commercialization, will become the future mainstream technologies.
