Abstract
In this paper, we designed and manufactured the distortion cancellation module which is able to compensate thermal-noise distortion by software The distortion cancellation algorithm not only bring forth system non-linear distortion by input level but also bring compensate component of distortion by thermal to get rid off distortion from now on. After TMS320C6711 DSP to recognize our algorithm, we manufactured the module for every kinds of system To evaluate efficiency of the distortion cancellation module, we designed and manufactured communication system. By measured result, if system output power is -3dBm equally, 12dB of ACLR has improved in 1MHz away from a center frequency, and also gain has increased up to 0.5dB.
