  Abstract

In this paper, we designed and manufactured the distortion-compensation module which is able to compensate thermal-noise distortion by LUT. The distortion-compensation algorithm not only bring forth system non-linear distortion by input level but also bring compensate component of distortion to get rid off distortion from now on. To evaluate efficiency of the distortion-compensation module, we designed and manufactured communication system. By measured result, if system output power is -3㏈m equally, 9㏈ of ACLR has improved in 1㎒ away from a center frequency, and also gain has increased up to 0.5㏈.
