The project deliverables are listed in the following.
1. DTMB Baseband System Design
• DTMB system specification
• Architecture design and hardware and software partition
• DTMB system interface design
• System Algorithm Development and Simulation, including synchronization, channel estimation and equalization, channel decoding, digital front end design, 3780 DFT, transmitter function to provide TS stream and DTMB signals.
Floating point and fixed point simulations for DTMB will be developed to verify and optimize the algorithm performance and design trade off. Appropriate simulation platform (test vectors and test benches) will also support RTL design verification by providing adequate test cases and test results.
2. DTMB Baseband FPGA Design
• FPGA architecture design
• FPGA Module Design and Implementation, including 3780 DFT, forward error correction, synchronization, channel estimation etc.
• Baseband FPGA Integration
3. Hardware Board Design
• FPGA demo board design, PCB layout, and integration. The board will be integrated and tested to demonstrate DTMB functionality and performance. Integration with RF tuner is optional at this stage.
• FPGA based system verification and testing
4. DTMB Baseband ASIC Design
• ASIC chip design specification
• ASIC chip architecture design
- Baseband architecture design includes architecture design in ASIC chip, as well as baseband board levels. Such architecture design takes overall design objectives (low power, cost, high efficiency and good performance, etc.) into account and optimize hardware resources and performance tradeoff in the architecture level.
• Front-End ASIC Design and Implementation, including FPGA to ASIC porting, RTL synthesis and Formal verification
• Back-End Design and Implementation, including static timing analysis and power analysis
• Test Chip Tape Out
Depending upon customer's demand, resource availability and schedule constraint, a test chip tape out would be considered.
5. IP Development and Patent Applications
At least two patents in the DTMB system and implementation will be generated in the project. Preliminary topics (may change or revise later depending upon the IP development progress) are listed below:
• DTMB PN removal and data compensation
• Hardware impairment correction methods
6. Industry contribution and sponsorship
We will actively seek for customers and partners and industry contribution for at least 10% of total budget in the entire project and continue after the end of project. The goal is to promote the technology and project deliverables and gain industry contribution for the project.

本項目的目標是為實現數字電視應用而開發的OFDM 技術和IPs。具體而言，該項目是基於中國地面數字電視標準DTMB，開發系統演算法和RTL IPs。除了針對中國地面標準DTMB(DMB-T)在IP 方面開發，本項目更強調在系統和硬體結構以及 DTMB 晶片設計，以獲得更具市場競爭力的IP 與產品。在這項研製過程中所建立的技術平臺和培養之技術專長，將為日後各種多模多功能技術及OFDM 相關的無線傳輸技術的研發道路奠定堅實基礎。 該項目的主要驅動力來自於巨大的市場機遇和技術創新。電視工業的技術革命近年來正在逐步展開。除了顯示技術由RCT 到等離子、LCD 再到LED，更重要而深刻的變化體現在模擬到數字技術的演進。這些技術更替使得標準清晰和高清晰能在更高效利用頻譜的同時，提供更高質量的接收。世界上各主要國家都對數字電視有了明確規劃，其發展是大勢所趨。鑒於全球現有逾8 億數量的電視機和10 億移動電話，可以預見在未來五到十年，其持續高增長的市場潛力不容小覷。 目前大多數數字地面和移動電視的國際標準都以OFDM 作為其傳輸技術。這進一步肯定了我們的研發內容和方向，同時也為我們提供了前所未有的機遇和絕佳的市場時機來進行創新並提高在業界的影響。我們將審慎地通過系統結構設計，演算法創新及仿真，FPGA 驗證，系統集成和性能測評等一系列步驟來確保該項目的順利完成。在項目初期階段我們還將與客戶和合作夥伴通力協作，使他們可以最大限度地受益於ASTRI 所提供的技術和IPs。近來成立的應科院-清華多媒體通信聯合實驗室使應科院從多年的研發成果和DTMB 專業技術中獲益匪淺, 最終把這項技術更快的推向市場。
