Feedback Reduction for Random Beamforming in Multiuser MIMO Broadcast Channel
For the multiuser multiple-input multiple-output (MIMO) downlink channel, the users feedback their channel state information (CSI) to help the base station (BS) schedule users and improve the system sum rate. However, this incurs a large aggregate feedback bandwidth which grows linearly with the number of users. In this paper, we propose a novel scheme to reduce the feedback load in a downlink ...
متن کاملRandom Beamforming in MIMO Broadcast Channels with Cooperating Receive Antennas
In a Gaussian multiple-input multiple-output (MIMO) broadcast channel, the sum rate capacity can be achieved by dirty paper coding (DPC). Nevertheless, DPC is computationally intensive and requires that full channel state information (CSI) from all users in the system is available at the transmitter. However, with partial CSI at the transmitter, random beamforming [1] can exploit the inherent m...
متن کاملA Random Beamforming technique in MIMO Broadcast Channels
In systems with a large number of transmit antennas M and a large number of users N, it is not always reasonable to assume that perfect channel knowledge can be made available to the transmitter. Since lack of channel knowledge does not lead to multi-user gains, it is therefore of interest to investigate transmission schemes that employ only partial channel state information (CSI). In this proj...
متن کاملZero-forcing DPC beamforming design for multiuser MIMO broadcast channels
The sum rate maximization in multiuser MIMO broadcast channels is investigated in this paper. We first propose an approach under a total power constraint. Compared with the most related methods in the literature, the proposed method can be easily adapted to a more realistic per-antenna power constraint. Since the power of each antenna is limited individually by the linearity of its power amplif...
متن کاملInterpolation Based Transmit Beamforming for MIMO-OFDM with Partial Feedback
Transmit beamforming with receive combining is a simple method for exploiting the significant diversity provided by multiple-input multiple-output (MIMO) systems, and the use of orthogonal frequency division multiplexing (OFDM) enables low complexity implementation of this scheme over frequency selective MIMO channels. Optimal beamforming requires channel state information in the form of the be...
