為了瞭解與實現多載波通訊技術，本研究探討正交多載波通訊收發機之架構與模擬方法，並且於軟體無線電平台產生實際多載波信號進行傳輸實驗與測試。在寬頻傳輸的多載波傳輸技術下，藉由軟體無線電平台傳輸多媒體資訊，以不同參數測試多媒體資訊的傳輸結果，以確定適當之傳輸參數設定方式，亦可以了解多載波通訊技術之運作方式與傳輸結果。研究過程中，於Linux系統下之GNU Radio通訊系統模擬軟體中進行多載波信號處理，建立可於軟體無線電平台上產生真實信號之程式架構，以圖片與聲音的媒體形式作為傳輸內容，實際發射與接收多載波信號，進而確認多媒體進行傳輸後的失真情形。於實驗結果中可以確認不同多媒體信號下，所需要的設定之取樣頻率與適當之傳輸封包大小，以獲得最正確的接收結果。

Multi-carrier communication techniques are studied and implemented in this research, where the real multi-carrier signals on the software defined radio (SDR) platform for transmission experiments and tests are generated. Based on the multi-carrier transmission technology, the multimedia information, including pictures and sounds, are transmitted through the software radio platform, and the transmission results with different parameters are received to show different sampling rates and data segment lengths of the SDR platform. Transceiver functions are built in GNU Radio software, which is operated under Linux, for software radio platform. The experiment results show that multi-carrier transceiver can successfully operate on SDR platform, and the multimedia data can be shown and recovered in the receiver side. The appropriate sampling frequency is 500kHz and the appropriate packet length is 16 units to obtain the most accurate reception results.
