MIMO(多數入多輸出)的訊號偵測在整個通訊架構中佔有非常重要的一環，它關係著整個通訊品質的好與壞。我們知道最大概似檢測(maximum-likelihood-detection, ML)為所有訊號檢測器中擁有最佳解的檢測器，但其計算複雜度也是最高的。如何有效降計算複雜度且保有一定的位元錯誤率(BER)，在這兩者之間取得一個權衡，是我們所追求的。在本篇論文中，我們將介紹如何有效達到上述之需求，並且在文末將呈現成果。

The MIMO detector plays a very important role in the communication structure. Detection
methods will directly affect the quality of communication. In this paper we compare the
difference between tree-search algorithm and random rounding-off algorithm, and combine
their advantages into hybrid search. In this process, we add the Lattice-Reduction to help us
to get better communication quality. Finally, we will present the results in the last chapter.
