摘要

In order to make full use of the transmission capability of the LEO satellite channel, this paper proposes a variable rate adaptive transmission scheme. We adopt rateless spinal codes to achieve a fine-grained bit rate and adopt the truncated incremental redundancy hybrid automatic repeat request (IR-HARQ) protocol to shorten the transmission delay of a certain message. A variable rate allocation (VRA) algorithm is proposed which uses the probability distribution of the number of symbols needed for successful decoding (the decoding CDF) of a packet and a dynamic programming strategy to calculate the optimal bit rate in every transmission attempt. Simulation results show that our proposed adaptive transmission scheme can increase average throughput by about 5.5% and 8.6% compared with the digital video broadcasting second generation (DVB-S2) standard when maximum transmission times are K=2 and K=3 respectively.
