Abstract

—By the increased number of antennas and power ampliﬁers connected to each in 5G system, the linearization methods like Digital Pre-Distortion (DPD) of each power ampliﬁer is inefﬁcient due to antenna imperfections such as crosstalk. Furthermore due to limited area the distance between antennas in array can vary, which leads to unwanted coupling between antennas. A solution to this problem can be treating the ampliﬁers and antennas as one system and linearizing the main beam signal at receiver rather than on each single power ampliﬁer. In the work described in this paper the whole system including ampliﬁers, antennas and receiver is treated as a 2-ports system and the impacts of above mentioned constraints are investigated.
