On the MIMO Capacity with Imperfect CSI
Multiple-input multiple-output (MIMO) antenna systems provide high capacity gain over a single-antenna system. This gain is maximised when channel state information (CSI) is available at the transmitter. In practice, however, only partial information could be obtained. In this paper, we shall present a study of the MIMO system capacity in the case of imperfect CSI. It is found that in the case ...
متن کاملMIMO-THP System with Imperfect CSI
In recent years, it was realized that designing wireless digital communication systems to more efficiently exploit the spatial domain of the transmission medium, allows for a significant increase of spectral efficiency. These systems, in general case, are known as Multiple Input Multiple Output (MIMO) systems and have received considerable attention of researchers and commercial companies due t...
متن کاملImplementation of SU-MIMO and MU-MIMOGTD-System under Imperfect CSI Knowledge
We study the performance of compressed beamforming weights feedback technique in generalized triangular decomposition (GTD) based MIMO system. GTD is a beamforming technique that enjoys QoS flexibility. The technique, however, will perform at its optimum only when the full knowledge of channel state information (CSI) is available at the transmitter. This would be impossible in the real system, ...
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 کاملRobust Optimization for MIMO Transmissions with Imperfect CSI
We investigate the problem of robust joint transmitter and receiver power allocation for uplink multiuser multi-input multi-output (MIMO) transmissions. The channel model is assumed to have Rayleigh flat fading. The objective of power allocation is to minimize the maximum MSE among all users each of which has limited transmit power. We investigate robust joint transmitter and receiver power all...
