To maximize file transfer from deep-space vehicles, a space-to-earth content-transfer protocol that combines turbo codes, RaptorQ codes, real-time channel prediction, and dynamic code-rate selection is proposed. The protocol features a signal-to-noise ratio prediction model that facilitates the periodic adjustment of turbo encoder to achieve adaptive-rate transmission, and fountain codes to eliminate retransmission of specific packets. Simulation results indicate that an increase of about 132% in file transfer rate is achievable compared to fixed-rate transmission scheme.

深空网络内容传输的动态编码选择方法

为了最大限度地从深空飞行器传输文件，提出了一种结合 Turbo 码、RaptorQ 码、实时信道预测和动态码率选择的空对地内容传输协议。该协议具有信噪比预测模型，可促进turbo编码器的周期性调整以实现自适应速率传输，以及喷泉码以消除特定数据包的重传。仿真结果表明，与固定速率传输方案相比，文件传输速率可提高约 132%。
