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.

This project aims to develop an OFDM Core and IPs for digital TV applications. More specifically, the project first aims to develop platform technology in system algorithms and RTL IPs for China terrestrial DTV standard DTMB. In addition to system IPs and core technology for the DTMB standard, the project also aims to develop baseband hardware and a DTMB test chip that lead to more competitive design and product offering in the market place. The underlying technology platform and expertise developed through this R&D endeavor will establish a solid foundation for various multi-mode multi-function technology initiatives and OFDM based radio transmission technologies well within the R&D roadmap. This project is primarily driven by enormous market opportunities as well as technology innovation. The television industry has underdone technology revolutions in recent years. In addition to display technology from CRT to plasma, LCD, then LED, the most significant change stems from the transition from analog technology to digital one. These technology shifts enable much more efficient spectrum utilization yet offer much better reception qualities with either standard definition (SD) or high definition (HD). Converting to digital TVs has a clear roadmap in various countries all over the world and is an inevitable and foreseeable trend. Given that there exist roughly 800 million TV sets and one billion mobile users in the world, the market potential is tremendous with continuous high growth for the next 5-10 years. Most of international standards for digital terrestrial and mobile TV utilize OFDM as its transmission technology. This further confirms our R&D mission and vision and in the mean time provides a unique opportunity and perfect market window to innovate and make substantial impacts. To assure accomplishing the project goal, a prudent systematic approach, through system architecture design, algorithm innovation and simulation, FPGA verification, and system integration and performance verification will be adopted. Customer and partner engagements will be carried out in the early stage of project so they can fully benefit from ASTRI's technology and IPs. Recently established, ASTRI-Tsinghua Multimedia Communication Joint Lab enables ASTRI to leverage and benefit from years of R&D efforts and DTMB technology expertise to bring this technology to consumer applications at faster pace.
