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.
