Equalizer In Digital Tv And Asic Implementation

DTV (Digital Television) technology integrates the most advanced image compressed encoding technology and the digital communication technology. It has become one of the focuses in the high-tech competitions. Having the imitative in this field will take the lead of high technology in the future, and get great chance in the growing market.Equalizer takes a key role in HDTV receiver. The focus of this paper is to analyze the algorithms and realization of equalizer, basing on the details of DVB (Digital Video Broadcasting) Systerm.In chapter one, the history of HDTV is introduced followed by DVB scheme.In chapter two and chapter three, the principle and algorithms of equalizer is introduced. A enhanced realization scheme of DVB-C is introduced by the simulation and comparation of some blind equalization algorithms.In chapter four, we discuss the criterion and design flow of a whole ASIC design and SOC design methodology. Verilog programming technique according to synthesis is introduced finally.In chapter five, we discuss the implementation of equalizer in the receiver ASIC. Then we introduce one better ASIC realization methods integrated with IP technique.
