In this paper we propose a novel trellis based

soft-input soft-output MIMO detector with significantly reduced search

space. The performance of the detector is measured by evaluating the

ultimate communication rate that is achievable for a system employing

the novel detector; this limit corresponds to a mutual information that

can be determined by standard methods. We also derive an expression

that bounds the mutual information of interest and that can be optimized by

numerical methods. Numerical results for many MIMO setups that illustrate the

performance of the detector are also provided.
