E-UTRA下鏈單點傳輸之多輸入多輸出技術概要

Overview of Multi-Input Multi-Output (MIMO) Technologies for Unicast Traffic in E-UTRA Downlink

摘要


多輸入多輸出技術被預期是在第三代通訊系統長程發展下用於下鏈進階通用無線接取中一個非常重要的構成要素之一。為達到進階通用無線接取之預期中的頻譜效益及傳輸能力,已有相當多的提案針對多重天線系統中的需求考量進行討論並做出結論。在取得這些提案的一致性前提下,吾人提供一個通用多輸入多輸出架構的概要性介紹。

並列摘要


Multi-input multi-output (MIMO) is expected to be an important component of long term evolution (LTE) of 3G systems particularly for the downlink Evolved Universal Terrestrial Radio Access (E-UTRA). To achieve the target spectral efficiency and throughput of E-UTRA, several proposals have discussed and concluded on the need for multiple antenna systems. In harmony with such proposals, we give an overview of general MIMO aspects.
