臺灣博碩士論文加值系統

本論文以IEEE 802.16e-2005無線通訊協定為基礎，實作低成本之WiMAX基頻（或中頻）產生器，產生符合標準的WiMAX訊框，作為WiMAX實體層模擬與測試之研究發展。由於WiMAX等寬頻無線系統對傳輸量和資料速率的要求，為了能夠支援高資料速率，基礎硬體平台必須有足夠的處理能力。因此，在硬體方面，本論文採用德州儀器TMS320DM6446 EVM搭配FPGA模組、DAC模組以及自製連接電路板。TMS320DM6446具有高效能的數值運算能力，並提供良好的開發環境，而FPGA具有高度靈活的可配置性，透過DSP和FPGA的結合實作出WiMAX基頻產生器。

This topic is based on IEEE 802.16e-2005 communication protocol, expect to implement the low cost WiMAX baseband (or intermediate frequency) generator, it can generate WiMAX frame that accords with standard, and can develop as one platform of simulation and research for WiMAX. In order to meet the demands of bandwidth transfer and throughput for wireless system, there must be enough ability in the basic hardware platform. In hardware, we adopt the TI’s TMS320DM6446 DSP chip, FPGA module, DAC module and the circuit board make by ourself for connection. DSP has the high ability of computation, and offers the good development environment. FPGA has highly flexible and disposition, because the standard is changing constantly too, make this platform more elastic through the combination of DSP and FPGA.
