摘要：
Aimed to realize reliable but time efficient data transmission in vulnerable space environment, an optimized sliding window transmission method based on BATS code (Batched Sparse Code) is proposed. In the scheme the unequal sliding step length of the window are used. While the small degree Batches are used to encode the data in the non-overlapping part of the window, the big degree Batches are used to encode the data in whole sliding window, and the probability distribution of the Batch degree is optimized through a heuristic algorithm. The results of the simulation experiment show that compared with the traditional successive sliding window, the transmission efficiency of our method is significantly improved, while the reliability is maintained at a similar level as the traditional method, hence the trade-off between the transmission reliability and time efficiency is improved.
