Abstract:	台灣採用歐洲廣播聯盟(European Broadcast Union, EBU)所制訂的數位電視廣播(Digital Video Broadcasting, DVB)規格，在本論文中，將以實務軟體定義無線電(Software-defined Radio,SDR)實現DVB-T接收機。實驗室結合FPGA板(A7)及射頻模組(AD9361)完成軟體定義無線電平台，並設計硬體進行DVB-T訊號解調，此接收機所需用到數位訊號處理模組包含降頻取樣、時間同步、頻率同步、快速傅立葉轉換、解訊框架構、通道估測器、通道等化器。先實錄訊號以MATLAB訊號解調，再選取相對應之硬體規格參數撰寫硬體描述語言，並用ModelSim模擬電路時序後，再以軟體無線電平台實錄訊號並驗證其硬體功能。便可用實務軟體定義無線電DVB-T基頻接收機於各地量測訊號並分析。;Digital Video Broadcasting - Terrestrial is a digital video broadcast standard adopted in Taiwan, and it is ratifies by European Broadcast Union. In this thesis, we implement the DVB-T Baseband Receiver with a Realistic Software-defined Radio platform. Our laboratory combine FPGA and Radio Frequency module(AD9361) to finish SDR platform. This baseband receiver need the digital signal processing units which are down sampling, time synchronizer, frequency synchronizer, Fast Fourier Transform processor, channel estimator, channel equlizer. First, recording DVB-T signal is programmed using MATLAB to demodulate the signal. Second, the specification for each digital signal processing units is designed, progrmaed by using Verilog hardware description language and verified with ModelSim. Then, the real-time haradware is implemented and verified with SDR platform. The measurement and analysis of recording signal in the difference places by DVB-T Baseband Receiver with a Realistic Software-defined Radio platform.
