Abstract

Deep space communications have such characteristics as long delay, high code error rate and easily broken links, etc. Easily broken links may lead to a certain degree of random flash-break of TT&C signals, which in turn will result in the unrecoverable loss of data. Luby Transform (LT) code (Luby in Proceedings of the 43rd Annual IEEE Symposium Foundations of Computer Science (FOCS), pp. 71–280 (2002)) technology is an excellent special data recovery technology for scattered data. It can solve the issue of data frame loss in deep space communications, and is very suitable for the reliable transmission of large volume of data, but it cannot improve the code error performance of transmission. Therefore considering the issues such as high code error rate and easily lost data in deep space communications, the paper studied and implemented the concatenation of LT code and LDPC/TPC code, expected to provide more reliable solution for the acquisition of deep space communications data.
