Optimal linear precoding in multi-user MIMO systems: A large system analysis
Optimal linear precoding in multi-user MIMO systems: A large system analysis
We consider the downlink of a single-cell multi-user MIMO system in which the base station makes use of $N$ antennas to communicate with $K$ single-antenna user equipments (UEs) randomly positioned in the coverage area. In particular, we focus on the problem of designing the optimal linear precoding for minimizing the …
