Research and Design a SFN Adapter of CMMB.

Abstract: A time synchronized SFN(Single Frequency Network) Adapter of CMMB(China Mobile Multimedia Broadcasting) system is proposed in this paper, which is designed based on the FPGA and associated with a PCI interface chip structure.This design improves the portability and upgrade performance of system by integrating all functions of the PCI controller,Adapter of SFN,ASI interface and GPS interface on one chip of FPGA and on chip of PCI interface.The process of design is described in detail and the implementation of the main functional modules is presented in this paper.
