The Design And Realization Of The Telemetry, Tracking And Signal Processing Hardware Platform Design And Bit Synchronizer

As a part of ADAS, author have designed,drew up and implemented signal processing hardware equipments and a code timing recovery circuit based PCI interface. The ADAS is important system receiving information of a moving object from far. As the control center of ADAS, signal processing hardware equipments is the key part which connecting other parts and making them working in order. The code synchronization pulse brought from code synchrolock has the synchronization benchmark heart function in the demodulation processing. At the same time, it is the base of frame demodulation and datum processing. The method of picking up synchronizated signal is digital phase-locked loop, which is picking up phase information from the suddenly toggle between codes. The dissertation introduces the system structure of the ADAS and depicts the processing of forming hardware equipments. The principal of the digital communication theory and the relational theory of the synchronization are introduced in fourth chapter. In fifth chapter, author detailedly describes the methods of two kind digital phase-locked loop, expounds the processing of design and implementation by FPGA. Author introduces PCI bus protocol briefly in the sixth chapter, has expounded the processing of design that PCI target interface and target logic control module. Finally, the circuit board is designed, the software and hardware debugging is performed. What main results in the project are listed as follows :Select the equipments platform which is suitable to ADAS.Complete the design of code synchronization module, carry the simulation and analyze the result.Write the target module according PCI 2.2 protocol and back end device logic storage module using HDL, carry the simulation and analyze the result.Design and implement the circuit board based PCI interface.
