Analysis of clustered SC-FDMA intermodulation distortion on LTE spectrum

In wireless communication system, power amplifier is essential in order to increase the signal to be transmitted. However, because of the non-linear system characteristic, the intermodulation distortion signals are generated as well. They can affect the system performance such as minimum sensitivity level and increase a block error rate. In this paper, we focus on a clustered SC-FDMA transmission intermodulation distortion on LTE commercial spectrum and investigate the effect of several-order intermodulation distortion.
