MULTIPLE-INPUT MULTIPLE-OUTPUT (MIMO) DETECTOR INCORPORATING EFFICIENT SIGNAL POINT SEARCH
摘要
<p>A novel and useful apparatus for and method of multiple input multiple output (MIMO) detection for use in MIMO based communication systems. The mechanism of the invention performs a simplified tree search utilizing a single stage expansion of the most likely first symbol candidates, in the case of a 2x2 MIMO system. The invention also provides a refinement mechanism that is operative to significantly improve the log likelihood (LLR) of the list of candidates. To improve the LLR, the mechanism applies refinements rounds to generate additional candidates for both first and second detected symbols.</p>
