Research On TPC Algorithm Of International Telecommunication Satellites And Common Platform Development

Channel coding plays an important part in wireless communication, channel coding Turbo codes cause a sensation because of its excellent error correction performance. Turbo Product Code(the TPC) is one type of Turbo codes using soft input and soft output iterative decoding algorithm. It is characterized by a strong anti-interference ability and excellent resistance to fading and efficient error correction performance. And its complexity and decoding latency lower than Turbo codes, which because of its sub-code is a linear block code, and it is suitable for high-speed communications because of its superior asymptotic performance.In the 21 st century, with the boom of the communication technology, basically every day there is a new communication. The quality and the speed of communication grows rapidly in the increasing demand of the appliers. Currently contradictory performance in satellite communications and high-speed bandwidth scarcity of transmission, in order to resolve this contradiction, improve the utilization of bandwidth, real-time signal transmission quality and transmission, Turbo product codes was born, and is widely used in satellite communications fields.The main content of this paper is : Giving brief description and analysis to several commonly used channel coding theory and algorithms, and then focus on the analysis and research for encoding and decoding algorithms of Turbo Product Codes, comparing some commonly used Turbo product Codes from the complexity and practical aspects of the performance of the algorithm. This paper compare three different BCH codes decoding and iterative simulation performance for sub-code product code, which made the new and improved Chase decoding algorithms and in-depth analysis influence the selection of the decoder algorithm performance advantages and disadvantages of different parameters; The new and improved article Chase algorithm for image transmission Encoding and conducted simulation experiments and data analysis software, thus contrasted Turbo Product Code iteration decoding algorithm has advantages in performance and other aspects.This paper theoretically analyzes the satellite communication Chase algorithm and innovative improvement and optimization, thus theoretically the actual communication has greatly improved the efficiency of encoding and decoding signals, and significantly improves the communication performance of the actual work and its applications has a very good sense of guidance and promotion.
