隨著無線通訊與嵌入式系統的快速發展,本論文主要目標於天線模組之系統整合及應用,現今無線區域網路的使用頻段十分擁擠雜亂,為了迎接物聯網發展趨勢與避免資料傳輸時的碰撞,我們建立一個能夠支援多頻段的無線收發平台,基於802.11a/g 網路通訊協定,使用正交分頻多工技術建立無線收發的系統於實驗板上,使用2×2天線收發封包,依據不同調變方式測試其錯誤率、吞吐量、距離與通道情況,進而運用在無線區域網路之中,作為未來邁向物聯網的先決條件。將 AD-FMCOMMS3 RF天線配合 Virtex 6 FPGA 開發板,藉由 SoC( System On Chip ) 設計電路於晶片內部,再透過韌體控制其收發狀態,完成802.11通訊協定的傳輸模式,天線接收後經由自行設計的電壓控制電路、SPI控制電路、同步電路與傳輸介面來使其能夠正常解碼。嵌入式項目包含硬體與軟韌體設計,硬件系統是基於 Microblaze 處理器和 FPGA 的組合,而軟韌體則是賽靈思提供之軟體開發工具包(SDK)。
In recent years, wireless communication and embedded system develop rapidly. We are going to focus on antenna module integration and application in this paper. The use of wireless LAN band is so crowded and messy nowadays that we set up a platform which can transmit or receive in multiband. We use 2×2 MIMO OFDM to implement wireless LAN based on 802.11 a/g. According to different modulation mode, verify the bit error rate, throughput, distance and channel condition. We can apply on Internet of Things ( IoT ). AD-FMCOMMS3 combine with Virtex 6 FPGA WARP v3 and build embedded system in FPGA by System on Chip (SoC). Then use firmware to control the mode of transmission and reception. When antenna received the 802.11 packet, the signal pass through voltage gain amplifier, SPI control, clock synchronization and transmission interface. The embedded system included hardware / firmware design, hardware based on Microblaze processor and FPGA design. Firmware is developed on Xilinx SDK.
