The traditional error control coding of channel has no long satisfied the requirement of the deep space communication, because of the long delay, great error rate, probability of packet loss, links easily interrupted and so on. The Fountain codes, used in deep space communication, has been introduced and analyzed. The coding and decoding process of LT codes of Fountain codes has been introduced and...
The features of long delay, great error rate and packet loss, asymmetric bandwidth between uplink and downlink and links easily interrupted in deep space communication determine the technology of encoding and decoding is a difficult issue. The basic conception and features of fountain codes are introduced, and the question of all-selected, degree distribution and the decoding algorithm of fountain...
