IEEE 802.15.3c 無線個人區域網路之單載波區塊傳輸基頻接收機的設計與模擬

Abstract

為了提供室內高速個人區域網路的需求，IEEE 802.15.3c的標準被制定出來。它兼採單載波區塊傳輸和正交頻分多工兩種調變方式，操作在60GHz免認證頻段，所提供的傳輸速率為1 Gbps以上。這篇論文將依據IEEE 802.15.3c標準內單載波區塊傳輸所規定的封包格式設計其基頻接收機架構，其中包含符元時序估計、通道估計、頻域等化器、及資料檢測等部分。每個部分將針對其運作原理及演算法做詳細的介紹，在每個部分中盡可能在性能表現與運算複雜度間取一平衡點。為了驗證接收機的效能，我們進行各種電腦模擬，特別在資料檢測的部分我們會提出各種方法來提升接收機在位元錯誤率上的表現，並計算其運算複雜度作為參考。最後我們提出結論與未來的研究方向。

The IEEE 802.15.3c WPAN standard was defined in order to support the demand of high data rate indoor transmission. It adopts SCBT and OFDM modulations and operates at 60 GHz unlicensed band. Hope to provide data rates more than 1 Gbps. In this thesis, we propose an IEEE 802.15.3c SCBT baseband receiver architecture according to its specified frame format. The receiver includes symbol timing estimation, channel estimation, frequency domain equalization, and data detection. We will describe the operation principles and the algorithms of each block in details. And we try to make a tradeoff between system performance and computation complexity. In order to verify the performance of the receiver, computer simulations are conducted under different conditions. Especially in data detection part, we propose several methods to enhance the performance of the receiver in BER, and we will calculate the complexity of computation as references as well. Finally, we draw conclusions and comments on possible future research directions.
