Abstract: Low earth orbit (LEO) satellite communications have become a research hotspot in the communication field in recent years due to its low latency, small path loss, and low-cost platform. With thousands to tens of thousands of satellites in the future LEO constellations, cooperative signal processing technology can tap the scale advantages of the mega constellation by utilizing the distributed transceiving and processing capability of multiple satellites, which makes it a promising technology to enable ubiquitous access in 6G.The recent research progress related to multi-satellite cooperative signal detection technology is analyzed, concerning both the technical routes and the implementation scenarios. Besides, the application prospect of multi-satellite cooperation technology based on the concept of the virtual array in LEO constellations is also explored.
Keywords: LEO constellations; multi-satellite cooperation; virtual array; signal detection
