Communication systems suffer from the mixed noise which contains both non-Gaussian impulsive noise (IN) and white Gaussian noise (WGN) in many scenarios. However, there is little literature on the channel capacity under the mixed noise. In this paper, we analyze the existence of the capacity under p-th moment constraint and prove that there are only finite mass points in capacity-achieving distribution. Furthermore, we discuss the capacity relating to specific modulation format under the mixed noise and derive a lower bound with closed form. Numerical results reveal that the capacity of the mixed noise channel will decrease as the impulsiveness of the mixed noise becomes significant and the obtained analytical capacity lower bound is tight.
