PAC Duo平台在多媒體應用的領域上已展現其優異的效能，但是在無線通訊系統的領域方面尚未開發及提供效能分析，由於目前眾多的無線通訊系統各有優勢，為了提供多模的方案，以可程式化的處理器單元(CPU/DSP)作為運算核心，可以有效降低成本並提高系統彈性。台灣地面數位電視廣播是採用歐規的DVB-T(Digital Video Broadcasting-Terrestrial)標準，本論文以PAC Duo平台實現結構較為單純的DVB-T接收機基頻處理器作為應用目標，探索以PAC Duo平台開發現代通訊系統的過程所遭遇的各種問題，並尋求解決之道。我們從系統規格制定出發，到模組的通訊演算法、PACDSP組語演算法的開發過程，以至最後的系統整合及優化等，提出各階段的建議流程及注意事項，期使將來PAC Duo平台應用於通訊系統的開發過程能少些阻力。

PAC Duo platform had good performance in multimedia area, however, no algorithm developed and evaluated in the communication system filed. Currently, many communication systems have their own superiority. In order to support the multi-communication modes system, programmable processor (CPU/DSP) is one popular solution which can easy adapt to different systems by replacing the software program. The hardware cost is reduced and the design flexibility is kept at the same time. The Digital Video Broadcasting-Terrestrial (DVB-T) standard defined by the European Broadcast Union (EBU) is adopted in Taiwan. In this article, we choose the DVB-T baseband receiver as the application target and implement with
the PAC Duo platform. We discuss the problems in developing the communication system with PAC Duo platform and the solutions. The contents include definition of system specification, algorithm of each
communication module, algorithm and development of PAC Duo assembly code, system integration and optimization.
