Abstract

In this paper we propose a new approach for the design of adaptive modulation and coding (AMC) for MIMO-OFDM wireless communications. We justify a possible conflict on the joint extraction of diversity and adaptation benefits of a MIMO-OFDM channel known at the transmitter. The proposed scheme avoids this conflict by adapting as accurately as possible given the side information while using diversity to combat remaining uncertainty. This is accomplished by channel parallelization, sorting and grouping into modulation modes. A new power allocation strategy, named WF/CI, is also introduced and showed to perform better than conventional water-filling in a practical setting. © 2006 IEEE.
