[Abstract]:Channel coding is an important part of data communication system. It is the main technology and method to transfer information reliably from the source to the receiver. Due to the maturity of FPGA hardware design, the development of technology, and the abundance of its internal resources, channel coding is the most important part of data communication system. The cost of developing digital circuits has been gradually reduced, the means of development have become more and more diverse, and the methods of use have become more and more flexible, so the implementation of channel coding on the platform of FPGA has become a real demand. The overall framework of the system platform is built, and the necessity and feasibility of using FPGA platform are demonstrated. Then, the FPGA program written in Verilog language is completed. Finally, the modelsim simulation platform of FPGA is built. The function and timing logic of the program are verified on the simulation platform. The subject is based on the actual demand and participates in the design and implementation of a data acquisition platform based on FPGA. The main functions of the platform are as follows: receiving the collected information data sent by the central processing module, encoding and modulating the data, sending the data to the satellite according to the pre-set channel, receiving the configuration parameter information sent by the central processing module; Send the configuration parameter information of the communication module itself and send it back to the central processor module according to the request. The platform is mainly arranged in the uninhabited areas such as mountains, islands, etc. It is necessary for the system to realize the serial connection between various coding structures. This paper mainly studies how to design and implement channel coding on the platform. In the part of channel coding, it focuses on BCH coding, convolutional coding and RS coding. The designed coding logic is simulated with MATLAB, and the correctness of the coded logic is verified by the simulation of MATLAB.
