軟體無線電數位電視廣播接收器類比數位轉換板實作

Implementation A/D board for PC-Based Software Radio DVB-T Receiver

指導教授 : 曾恕銘

摘要


在本文中,我們針對地面數位電視廣播(DVB-T)接收器,提出一塊類比數位轉換板,這張板子是由調諧器、8位元類比數位轉晶片與PCI介面的位元串擷取卡組合而成,以滿足我們在軟體無線電數位電視接收器程式開發上的需求。由成果證明此類比數位轉換板架構,可在靜止通道下成功取樣DVB-T訊號,另利用調整參考電壓與中頻訊號增益值的方式,以匹配8位元量化解析的動態區間,使整個架構有效降低取樣資料量與軟體程式運算量,進而增加軟體程式解譯速度,最重要不失取樣精確度。

In the paper, we propose the AD board architecture for PC-based software DVB-T receiver. It includes a tuner board, AD board and commercial PCI acquisition board. And it can satisfy our research requirement of software receiver. After our experiment, the AD board architecture can successful record DVB-T signal on the static channel. We set the optimal IF AGC value and reference value of ADC to match the 8 bits resolution dynamic range. And then, the sampling accuracy is very well.
