This paper proposes a novel uplink power control scheme in a single cell for massive MIMO (Multiple-Input-Multiple-Output). The proposed algorithm exploits the spatial degrees of freedom provided by massive MIMO to achieve the highest signal to interference-plus-noise ratio (SINR) for each user by considering the mutual spatial correlation arising from other users. It also minimizes the required uplink...
MIMO is one of the techniques used in LTE Release 8 to achieve very high data rates. A field trial was performed in a pre-commercial LTE network. The objective is to investigate how well MIMO works with realistically designed handhelds in band 13 (746-756 MHz in downlink). In total, three different handheld designs were tested using antenna mockups. In addition to the mockups, a reference antenna...
The application of multiple-input multiple-output (MIMO) in body-area networks (BAN) is considered in the paper. The correlations between MIMO sub-channels and the MIMO channel capacity are investigated for three on-body channels when random movements are performed in an indoor environment. Some of the MIMO sub-channels were found to be correlated. Nevertheless, a significant capacity increase due...
This paper investigates the effect of the antenna (polarization diversity (PD) or space diversity (SD)) configuration at evolved Node B and antenna angle of user equipment (UE) on the throughput performance of multiple input multiple output (MIMO) in Evolved UMTS Terrestrial Radio Access (E-UTRA) field experimental system. The results show that the throughput performance as a function of the measured...
