Abstract
Packet retransmission strategies are presented for MIMO eigenmode
transmission where adaptive modulation and coding (AMC) is
implemented. The retransmission design is based on weighted linear
MMSE. It includes the transmit and receiver filter, the power and
eigenmode allocation and AMC level when new packets are
transmitted. The weight matrix of WMMSE is used to appropriately
weight streams with different AMC levels in order to maximize the
system throughput. Simulations show that the choice of the weight
factors has a major impact on the performance.
