Abstract
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.
