摘要

LTE-A (Long Term Evolution Advanced)為未來無線通訊發展的重要方向，它是是由第三代合作夥伴計劃(3rd Generation Partnership Project；3GPP)所制定的第四代行動通信技術標準LTE的新發展方向。本論文主要探討LTE-A之實體層(Physical Layer)的系統架構。從實體層在LTE-A架構中的位置開始介紹，說明實體層與上層之間的關聯，再對LTE-A的訊框架構(Frame Structure)和下行(Downlink)訊號進行介紹。接著介紹下行傳送端實體層的基本系統架構，並將整個基本架構流程中的區塊詳細敘述。最後分別對LTE-A下行實體層中的五種實體通道(Physical Channel)與基本系統架構的不同之處進行說明。

LTE-A (Long Term Evolution Advanced) is an important direction in the future,it is development of wireless communication by the Third Generation Partnership Project (3GPP) developed by the fourth generation mobile communication technology standards. In this paper, we discuss the system architecture of the LTE-A physical layer. From the physical layer in the architecture of the LTE-A began to introduce and explain the association between physical layer and the upper re-introduction of the LTE-A frame structure and downstream signal. Then,we introduce the downlink transmit of the physical layer basic system architecture, and in the process of the basic architecture of each block in detail above classification. Finally, the LTE-A downlink physical layer of the five physical layer channel and basic system architecture is described.
