    This deliverable is the final deliverable of workpackage 3 “MU-MIMO in practice”. It builds on the previous deliverables D3.1 and D3.2 and includes results tasks 3.2 on channel modelling for MU-MIMO (Note that this task has been extended to month 24) and task 3.3 on the implementation of the selected MU-MIMO algorithms on the OpenAirInterface development platform.
