摘要

欧空局光学混合项目的目标是实现用于空间任务的高光子效率(HPE)链路的面包板，符合CCSDS推荐的光通信标准。重点讨论了物理层和编码调制层。该规范的目标是高光子效率，这是一个重要的新方面。因此，对下行物理层的仿真是本项目的基础。信号处理部分在SDR平台上实现，该平台能够生成和处理长度为2ns的SCPPM调制脉冲。在项目的第一个阶段，建立了端到端系统模拟。在本文的背景下给出了性能结果。

Results from a CCSDS-compliant High Photon Efficiency Downlink SDR Platform

Target of the ESA project Optical Hybrid is a breadboard implementation of a high photon efficiency (HPE) link for space missions, compliant with the CCSDS recommended standard for optical communication. Especially the physical layer and coding and modulation layer are considered. The specification is targeting high photon efficiency, which is an important new aspect. Therefore the emulation of the downlink physical layer is a baseline in the project. The signal processing part was implemented on a SDR platform, which is able to generate and process SCPPM modulated pulses down to 2ns length. In the first project phase an end-to-end system simulation was setup. Performance results are presented in the context of this paper.
