Abstract

Whereas in the previous chapter we considered a single-user MIMO link where data streams intended for a single user are multiplexed spatially, in this chapter we consider multiuser MIMO channels where data streams to/from multiple users are multiplexed in this way. In particular, we consider two multiuser Gaussian MIMO channels that are relevant for cellular networks. The uplink can be modeled by the Gaussian MIMO multiple-access channel (MAC), a many-to-one network where independent signals from K >1 users are received by a single base receiver. The downlink can be modeled by the Gaussian MIMO broadcast channel (BC), a one-to-many network where a single base transmitter serves K > 1 users. To avoid needless repetition, we will henceforth drop the “Gaussian MIMO” qualifier when referring to these channels.
