Multi-User MIMO communication for Local Area scenarios: 4G system design for an indoor
(enterprise) communication scenario using distributed antennas; including:
linear precoding (regularized block diagonalization or Successive MMSE) in the downlink, linear decoding
(regularized block diagonalization or Successive MMSE) and non-linear decoding
(successive interference cancellation) in the uplink, pilots and channel estimation (spatial pilot reuse),
scheduling and resource allocation (opportunistic, Proportional Fair). This work was carried
out within the European research project WINNER-2.
MIMO strategies for voluntary infrastructure sharing between operators in the multi-pair two-way relaying
and the multi-pair interference channel settings. This work was carried
out within the European research project SAPHYRE.
