| dc.description.abstract | DVB-T數位電視廣播採用的正交分頻多工(OFDM)調變技術，此技術具有抗多重路徑干擾、高效率頻譜使用率、高速率傳輸及對抗頻率選擇的通道衰減等優異特性。
由於許多研究都是假設干擾，需自行產生合理的干擾源，去模擬現實生活中的訊號，此篇論文主要在建置DVB-T訊號錄製平台，可用來路測、環境測試等等，來實際分析現實生活中的各種訊號，本篇論文也會介紹到平台製作過程及程式流程，最後可用錄製下來的檔案給Matlab分析訊號的狀況，以便研究訊號在各種環境上的特性，而我主要分析靜態環境和動態訊號的差異和狀況。平台製作主要是利用商用Tuner、ADC和FPGA，將資料轉換成二進制碼，再透過USB將資料傳給PC。

| dc.description.abstract | The Digital Video Broadcasting – Terrestrial (DVB-T) has adopted the Orthogonal Frequency-Division Multiplexing (OFDM) that exhibit many features in terms of anti-multiple-access interference, superior efficiency of spectral utilization, high speed transmission and against inevitable frequency-selective fading.
Many researchers have hypotheses of interference, and they need to generate sources of interference to simulate signals in the surroundings. This research is to setup a platform of DVB-T signal recording for analyzing various signals. It could be applied to the road test, environment test and so on. In this research, it would also present the process of platform establishment and program procedure. The recorded files from this platform could be adopted by MATLAB to analyze characteristics of signals in different environments. This research is purposed to analyze the difference and performance of static environment and dynamic signal. The platform uses business Tuner, ADC and FPGA to convert the data to Binary code, and then transmit the data to PC through USB.
