MIMO Testbed for MU-MIMO Downlink Transmission
Multi-user multiple input multiple output (MU-MIMO) systems have attracted much attention as a technology that enhances the total system capacity by generating a virtual MIMO channel between a base station and multiple terminal stations. Extensive evaluations are still needed because there are many more system parameters inMU-MIMO than in single user (SU)-MIMO and the MU-MIMO performance in act...
متن کاملLinear Precoding Performance of Massive MU - MIMO Downlink System
Nowadays, multiuser Multiple-In Multiple-Out systems (MU-MIMO) are used in a new generation wireless technologies. Due to that wireless technology improvement is ongoing, the numbers of users and applications increase rapidly. Then, wireless communications need the high data rate and link reliability at the same time. Therefore, MU-MIMO improvements have to consider 1) providing the high data r...
متن کاملAdaptive Opportunistic Transmission in MU-MIMO Downlink with Reduced Feedback
In this paper we proposed two threshold-aided adaptive opportunistic transmission strategies in multiuser multiple-input multiple-output (MU-MIMO) downlink with limited feedback. Threshold scheme in company with transmission mode adaptation are employed to handle feedback cost and improve system performance. In one time slot, each mobile station (MS) carries out channel estimation, selects appr...
متن کاملRobust Transmission for Massive MIMO Downlink with Imperfect CSI
In this paper, the design of robust linear precoders for the massive multi-input multi-output (MIMO) downlink with imperfect channel state information (CSI) is investigated, where each user equipment (UE) is equipped with multiple antennas. The imperfect CSI for each UE obtained at the BS is modeled as statistical CSI under a jointly correlated channel model with both channel mean and channel v...
متن کاملNetwork MIMO Downlink Transmission
The effects of cooperating base stations in the downlink of an OFDM-based cellular network with frequency reuse factor one are studied. In this so-called network MIMO scenario the signals of several users are jointly processed before transmission in order to handle the unavoidable multi-user interference. We apply and study pre-processing techniques well-known from conventional MIMO scenarios i...
