  In recent years and with introduction of 5G cellular network and
communication, researchers have shown great interest in Multiple Input Multiple
Output (MIMO) communication, an advanced technology. Many studies have examined
the problem of designing the beampattern for MIMO communication using uniform
arrays and the covariance-based method to concentrate the transmitted power to
the users. However, this paper aims to tackle this issue in the context of
non-uniform arrays. Previous authors have primarily focused on designing the
transmitted beampattern based on the cross-correlation matrix of transmitted
signal elements. In contrast, this paper suggests optimizing the positions of
transmitted antennas along with the cross-correlation matrix. This approach is
expected to produce better results.
