A novel soft-input soft-output reduced complexity MIMO trellis detector
Author
Summary, in English
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.
