WIMAX(Worldwide Interoperability for Microwave Access) 的縮寫,一般中譯為「全球互通微波存取」),是一種新興無線寬頻傳輸技術。在WIMAX 系統由三個部份組成,包括通道編碼、調變和正交分頻多工。然而一個正交分頻多工對於會產生大量載波間干擾的時間或頻率偏移是相當敏感的,造成系統效能大幅下降。在本論文中,我們以硬體描述語言Verilog HDL 實現同步系統,並將以建構好的物件燒錄到Vertex-4的FPGA開發版上,並且量測它的效能。

Wimax,the abbreviation of "World Interoperability for Microwave Access", is an emerging technique of wireless communication. In Wimax system, it is composed of three parts, including channel coding, modulation, and orthogonal frequency division multiplexing (OFDM) system. However an OFDM system is very sensitive synchronization and a small frequency or timing offset may cause a large inter-carrier interference (ICI), lead to dramatic degradation in the system. In the thesis, we implement the synchronization system with Verilog HDL. The result model will download to Xilinx Vertex-4 FPGA development board and evaluate its performance.
