Design And Implementation Of RS Decoder And Convolution Code Synchronizer In DVB-S

With the development of the digital broadcasting technology, Digital video broadcasting-satellite (DVB-S) is adopted by many countries as their national broadcasting standard because of its unique features such as its capability to provide long-distance and high-performance service. The paper will discuss the following problems in sequence within the design of DVB-S base-band receive chip's key module: RS decoder and convolution code synchronizer.1. Briefly introduce the development of RS code and its decoding algorithm.2. Analyze the algorithm of RS decoding in detail.3. Analyze the architecture to implement the decoding module in finite field. Specifically to adapt to DVB-S system, propose a new decoder structure.4. Give its front-end design flow of the decoder and optimization.5. Briefly introduce the development of the convolution system's node synchronization.6. Introduce a relatively new synchronization method, and analyze its algorithm as well as implement.
