The development of digital TV has been the focus of global broadcasting of TV and the development of electron technology enable the realization of ASIC. DVB-S channel receiver chip is a perfect combination of two. Carrier recovery module of DVB-S channel decoder chip will be deep discussed In this articleIn the chapter one, digital TV standards is introduced here and DVB-S channel transimission standard is introduced in detail. What's more, ASIC solution and procedure are discussed.In the chapter two, the compenent of DVB-S receiver system is introduced and the whole chip solution is given.Chapter three consists of the common theory of modulation and de-modulation, PLL and QPSK modulation.Chapter four gives the algorithm and implement of digital carrier recovery of DVB-S channel decoder chip.Synthesis, DFT and verification technologies are introduced for ASIC implement in the chapter five. |
