Large System Analysis of Linear Precoding in Correlated MISO Broadcast Channels Under Limited Feedback
Large System Analysis of Linear Precoding in Correlated MISO Broadcast Channels Under Limited Feedback
In this paper, we study the sum rate performance of zero-forcing (ZF) and regularized ZF (RZF) precoding in large MISO broadcast systems under the assumptions of imperfect channel state information at the transmitter and per-user channel transmit correlation. Our analysis assumes that the number of transmit antennas $M$ and the …
