Downlinks for Future Earth Observation Satellites: Breaking the Bottlenecks

点击翻译按钮获取中文摘要

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.
