[Invited Talk] Distortion Compensation Circuit Techniques for Radio Frequency Transmitters
Noriharu Suematsu (Tohoku Univ.) WBS2012-9 SAT2012-8
Abstract (in Japanese) (See Japanese page) 
(in English) Distortion components in transmitted signals are mainly generated due to the nonlinearities of high power amplifier of radio frequency transmitters. Since the distortion degrades the modulation characteristics (such as Error Vector Magnitude, EVM) and interferes neighborhood users in the next channels, the distortion compensation techniques are important. In this paper, the basis of various types of distortion compensation techniques is described and some of the examples are introduced with actual applications.
