Downlinks for Future Earth Observation Satellites: Breaking the Bottlenecks

未来的地球观测卫星需要更高频段的千兆传输速率。无线电频谱的限制要求频谱效率调制方案，这使得千兆数据速率特别具有挑战性。该项目旨在为未来的ka波段千兆卫星下行链路设计下一代传输方案，包括处理信道效应（如群延迟、纹波和非线性卫星功率放大器）的新方法。该设计旨在包括高速信号处理和编码架构，以及实时信号合成和采集，以便与泰雷兹阿莱尼亚航天公司的卫星硬件进行实际性能测试和优化。

Future earth-observation satellites require gigabit transmission rates in higher frequency bands. Limitations in the radio frequency spectrum call for spectrally-efficient modulation schemes, which make gigabit data rates particularly challenging. This project aims to design a next-generation transmission scheme for future Ka-Band gigabit satellite downlinks, including novel approaches for dealing with channel effects such as group delay, ripple and non-linear satellite power amplifiers. The design intends to include high-speed signal processing and coding architectures, plus real-time signal synthesis and acquisition to allow realistic performance testing and optimisation with satellite hardware from Thales Alenia Space.
