Large-Scale MIMO Versus Network MIMO for Multicell Interference Mitigation
Large-Scale MIMO Versus Network MIMO for Multicell Interference Mitigation
This paper compares two important downlink multicell interference mitigation techniques, namely, large-scale (LS) multiple-input multiple-output (MIMO) and network MIMO. We consider a cooperative wireless cellular system operating in time-division duplex (TDD) mode, wherein each cooperating cluster includes $B$ base-stations (BSs), each equipped with multiple antennas and scheduling $K$ single-antenna users. …
