    Large Scale (Massive) MIMO enhances the advantages of the conventional MIMO in terms of data rate, energy efficiency and reliability. To increase the scalability of conventional massive MIMO, the distributed large scale MIMO is recommended. Synchronization for distributed large scale MIMO is needed due to the lack of common clock source to synchronize the transmitters. Limited Inter-User Connected Interference Alignment for K-User is proposed for Large Scale MU-MIMO precoding scheme. Moreover, we discuss phase rotation factor estimation and compensation to synchronize the distributed large scale MIMO. The Interference Alignment algorithm with antenna selection also employed to show the effect of the synchronization in distributed large scale MIMO performance.
