60GHz室內無線通訊之電波傳播模式、通道量測及傳輸效能模擬

現今的無線通訊產業快速發展，朝向寬頻以及高傳輸速度的方向前進。60GHz頻段具有成為下一代無線區域網路的優質潛力，因為在此頻段，已有一段寬廣的頻譜在世界各地被指配。本論文將致力於此頻帶的電波傳播模型、通道量測以及系統效能模擬分析。基於系統效能模擬考量，我們提出一個有關建立室內寬頻通道模型的方法，並將這模型使用於60GHz頻帶。藉由實地量測以及電腦模擬，我們成它a驗證這個通道模型的可行性及正確性。除此之外，在60GHz這個頻段的通道特性也經由量測以及模擬工作而得到更多的瞭解。我們提出以下建議，未來系統操作應當在接收端配備方向性天線以提高通訊品質且提供合理的系統涵遢d圍。系統效能及涵遢d圍分析顯示高傳輸速度可以在合理的距離內達成。另外，人員阻擋將會嚴重地降低系統效能及系統涵遢d圍。

Emerging demand for broadband and high data rates application has stimulated rapid development of wireless industry of nowadays. The 60 GHz band is expected to be a candidate for next-generation WLAN system since a wide range of spectrum has been allocated worldwide. In this thesis, propagation model, channel measurement and system simulation at the 60 GHz band will be studied. For the purpose of simulation of system performance, we have proposed a methodology about indoor wideband channel modeling, which will be extended to 60 GHz band. With practical works of measurement and computer simulation, we have successfully verified the feasibility and correctness of the proposed indoor channel model. In addition, fundamental channel characteristics of 60 GHz band are more understood by going through practical measurement and simulation works. We suggest that directive antennas should be equipped at the receiver end to provide reasonable link quality and system coverage. From the analysis of BER performance and link budget, it reveals that high data rates can be achieved with reasonable system coverage. Besides, human blockage will seriously degrade the system performance and reduce the area coverage.
