Performance comparison between Single-User MIMO and Multi-User MIMO in wireless mesh networks

In this paper, we propose applying to MU-MIMO (Multi-User Multiple-Input Multiple-Output) to wireless mesh networks. If the number of packets which have the same receiving node are not enough, SU-MIMO (Single-User MIMO) cannot take an advantage of the capacity enhancement by the spatial multiplexing. By contrast, MU-MIMO is expected to enlarge the efficiency because it can simultaneously transmit packets to multiple receiving nodes. The hidden...
