1Achieving High Data Rates in a Distributed MIMO System Horia Vlad Balan Ryan RogalinAntonios Michaloliakos Konstantinos PsounisGiuseppe CaireUSC
2Structure of this talk Motivation Multiuser MIMO and precoding schemes Distributed MIMO and synchronizationExperimental results
3[Webb - The Future of Wireless Communication] MotivationCellular companies spend billions for more bandwidthSpectrum reuse is the most promising way to increase wireless transfer rates and distributed MIMO is its ideal implementationIn WiFi networks, with a high number of users, spectrum reuse becomes equally important[Webb - The Future of Wireless Communication]
27(85% of the theoretical gain) ResultsTomlinson Harashima85% rate increase(85% of the theoretical gain)(2x2 MIMO)
28(55% of the theoretical gain) ResultsTomlinson Harashima165% rate increase(55% of the theoretical gain)(4x4 MIMO)
29Results Blind Interference Alignment 22% rate increase (66% of the theoretical gain)
30MAC Layer ResultsComparing scheduling strategies through simulation in a 4 AP, 8 users scenarioGreedy Zero-Forcing, Tomlinson-Harashima precoding, Blind Interference AlignmentUsing TDMA as a reference point.
