%X A joint optimized preprocessing for sphere decoder is proposed for MIMO systems. The key idea of optimization is to firstly determine the initial radius and optimal detection order in a joint approach by running an ordered zero forcing decision feedback equalizer (OZF-DFE detector which is embedded in the regular sphere decoder. A minor improvement on the body of sphere decoder is also introduced in this paper. The simulation shows that complexity of the joint optimized sphere decoder is lower than others.
