摘要：
This paper investigates the performance of hybrid ARQ schemes for the mobile Low Earth Orbit (LEO) satellite channel. The proposed schemes adapt their characteristics to the time-varying behavior of the channel. To obtain an unbiased comparison of different ARQ schemes an approximated analytical method is adopted. More precisely, the sphere-packing bound is used to estimate the best possible performance of a hybrid ARQ scheme. To assess the accuracy of the bound, simulation results, based on the use of turbo codes, are also presented.
