Robust 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 کاملOn 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 کاملDeep Learning for Massive MIMO CSI Feedback
In frequency division duplex mode, the downlink channel state information (CSI) should be sent to the base station through feedback links so that the potential gains of a massive multiple-input multiple-output can be exhibited. However, such a transmission is hindered by excessive feedback overhead. In this letter, we use deep learning technology to develop CsiNet, a novel CSI sensing and recov...
متن کاملDownlink Precoding with Mixed Statistical and Imperfect Instantaneous CSI for Massive MIMO Systems
In this paper, the feasibility of a new downlink transmission mode in massive multi-input multi-output (MIMO) systems is investigated with two types of users, i.e., the users with only statistical channel state information (CSI) and the users with imperfect instantaneous CSI. The problem of downlink precoding design with mixed utilization of statistical and imperfect instantaneous CSI is addres...
