Summary:PURPOSE: A signal detection device for a multiple input multiple output wireless communications system and a method for the same are provided to reduce the search space of a candidate vector set for reducing calculation amount, thereby calculating an optimal LLR value. CONSTITUTION: A candidate symbol generation unit(110) generates a first candidate vector set. The candidate symbol generating unit generates a second candidate vector set. The second candidate vector set is a candidate vector set about the generated first candidate vector set. A Euclidean calculator(120) generates a final candidate vector by comparing the first candidate vector set and the second candidate vector set. The Euclidean calculator detects an ML solution by calculating a Euclidean distance.
