Based On The Dvb-c Digital Qam Receiver And Its Carrier Recovery

This project is aimed at designing an all digitized QAM receiver chip based on DVB-C system with the cooperation of Chengdu Chinaray Microelectronic Co.Ltd. and the verification based on FPGA must be accomplished. the core tasks includes designing matching filter,carrier recovery and timing synchronization,symbol synchronization and blind adaptive equalizer of all digitized QAM receiver.This paper will introduce the principle of the DVB-C series standards firstly, then the sketchy design of the system will be stated. At last, the software and hardware parts of the carrier recovery will be discussed in detail, especially its design with FPGA design . What I have done in the project are listed below : A): Collect the information and paper on DVB-C and get familiar with the total DVB-C system.B): design the total shceme of QAM receiver based on DVB-C. C): Create the simulation data received of QAM receiver. Complete the design of carrier recovery of software simulation system。 D): Using Verilog HDL language to implement carrier recovery programming ,testing and debugging.E): Take part in software and hardware system testing and debugging.The Verilog code verification is accomplished successfully.
