Abstract: A method performed by a sphere decoder based turbo equalizer for reducing interference of a parent QAM symbol from a received signal is provide. The method comprises assorting in a first vector QAM symbols on a particular tree level based on first distance properties, assorting in a second vector QAM symbols on the particular tree level based on second distance properties, selecting the QAM symbol with the minimum distance property in the second vector, identifying the selected QAM symbol in the first vector assorted by distance properties, pruning the first vector by eliminating all QAM symbols having a larger distance property compared to the selected QAM symbol.
