摘要

3GPP LTE-A (long term evolution-advanced) 4G系統的標準制定已經底定，Rel-12 版本已於2014年Q2完成，全世界3GPP LTE/LTE-A網路的建設也不斷的在擴大、成長。同時，第五代(5th Generation, 5G)行動通訊系統的研發，也開始成為世界各大廠競技的焦點。若想要與世界接軌，就必須要有一個符合國際標準的模擬平台，來評估在系統研究和設計上的系統效能，有鑑於此，本研究著重在於基於技術報告3GPP TR 36.873: “Study on 3D channel model for LTE”的規範下，建立出一個具有Wrapped Around和相關性大尺度參數 (Large scale parameters Correlation)特性的三維空間通道模型 (Spatial Channel Model)，使得在研究LTE-A系統的時候，可以得到具有空間特性的通道響應，進而使得在評估具有大型天線下的系統效能能夠更加準確，且本文對於模擬平台中使用到的網路拓樸、產生具有相關性大尺度參數和鏈路參數的實作上會有更詳細的介紹。

Formulation of the 3GPP long term evolution-advanced (LTE-A) 4G system standard is almost complete, Release 12 was completed in the second quarter of 2014, and construction of the 3GPP LTE/LTE-A network infrastructure continues to expand and undergo development worldwide. Concurrently, research on 5G mobile communication systems is becoming a central concern among major companies around the world. To achieve international competitiveness, companies must build a simulator to evaluate the system performance of research and design outcomes. Accordingly, this paper focuses on the construction of a spatial channel model simulator that conforms to international standards by utilizing the wraparound method and large-scale parameter correlations. The proposed simulator was based on 3GPP TR 36.873 (“Study on 3D channel model for LTE”) for generating channel response with appropriate spatial properties. System performance was evaluated using a 2D plane antenna to improve the accuracy. This paper discusses the implementation details regarding the network topology, correlated large-scale parameters, and link parameters.
