A Low-Complexity SDMA Grouping Strategy for the Downlink of Multi-User MIMO Systems
, 2006 In this work, a sub-optimal space division multiple access (SDMA) grouping strategy is proposed for the downlink of multi-user MIMO systems. It uses a new spatial compatibility check metric to estimate the grouping efficiency without needing to compute ...
