Abstract
With the progress of human civilization and the development of society, aerospace technology is more and more widely used in people’s daily life, but the channel coding based on spacecraft has not been widely used. Channel coding recognition technology is to identify the parameters of the received coding sequence in the case of unknown or known partial prior knowledge, which has a very broad application prospect. It can improve the spectrum efficiency of cooperative communication based on spacecraft and meet the needs of communication reconnaissance. It is necessary to analyze the coding type and parameters of received data, so that the receiver can make effective response. This paper briefly introduces the model, architecture and core functions of channel coding based on spacecraft application, analyzes the structure and function of spacecraft channel coding, introduces the design principle of channel coding system, and explains the necessity of using channel coding identification method for spacecraft. The analysis shows that the channel coding recognition method based on spacecraft has a great development prospect in this field. The recognition algorithm based on Viterbi decoding proposed in this paper has a correct rate of over 97% in 1/3 error resistant codes.
