Abstract:	國際5G系統規格制訂已經正式開始，世界各國皆已開始投入其中。METIS為歐盟研究5G的一項大型計畫，其研究之內容很有可能收錄在未來5G的國際標準規範中，由於現有的通道模型已無法滿足5G系統之要求，因此METIS基於測量與分析數據開發了新的通道模型，本文為根據METIS D1.4 “Initial channel models based on measurements”[1] 中的Map-based channel model(地形資訊通道模型)進行研究，以馬德里地圖為模型建立其環境，並使用簡易的射線追蹤技術(ray-tracing technique)模擬出電磁波的傳輸路徑，便可得知不同傳輸路徑下的路徑損失及電磁波發射、接收之角度，進而分析其傳輸通道的情況。 The specifications of 5G communication systems has been officially started. Every countries around the world have begun to invest it. Since none of the existing channel models in the literature satisfies 5G systems’ requirement, METIS develop new channel models based on extensive measurement campaigns and analysis com-plemented by computer simulations. In this paper, our research is according to Map-based channel model in METIS D1.4 ”Initial channel models based on meas-urements”[1]. Using the Madrid map as a model to establish simulation environment, and using simple ray-tracing technique to simulate the transmission path from transmitter to receiver. Then we can know the pathloss and angle of arrival/departure for different transmission path. Finally we can get channel impulse responses to analyze the transmission channel.
