Efficient MAC for Distributed Multiuser MIMO Systems
A distributed multiuser MIMO system consists of several access points which are connected to coordinating servers and operate as a large multi-antenna access point. Thanks to joint decoding and precoding, all transmitted signal power is useful, rather than "Interference". The system has the potential to support constant rates as the number of clients increases, thus offering a tremendous bandwidth boost. Despite the high gains and potential applicability to real world setups like enterprise networks, this approach is regarded today mostly as a theoretical solution because of some serious implementation difficulties.
