Abstract:
In this paper, we proposed a joint design scheme between sphere decoding and user scheduling for multiuser MIMO uplink system. This is a cross layer design scheme which adopt the channel quality information based on user scheduling to reduced the search radius of sphere detector, it leads the better bit error ratio performance and low complexity than conventional sphere detection with fixed search radius. © 2008 IEEE.
