Modern communication systems suffer from the nonnegligible distortion caused by the inherent nonlinearity of high-power amplifiers (HPAs). As such, many methods have been proposed to mitigate this nonlinear effect. However, their performances are seldom compared, and their practicalities are rarely evaluated. In this paper, experimental setups to investigate two popular types of HPA systems have been developed: 1) the traveling wave tube amplifiers and 2) the solid-state power amplifiers… CONTINUE READING
