Sammanfattning

In this paper we derive and evaluate by receiver tests a method for
pruning tree representations of MIMO signals. The efficiency of the method is compared to
that of standard tree pruning used for sphere decoders for several different MIMO system
setups. The outcome is that savings up to 50\% compared to the
standard sphere decoder are possible.
