Democratizing LEO Satellite Network Measurement
Proceedings of the ACM on Measurement and Analysis of Computing SystemsLow Earth Orbit (LEO) satellite networks are quickly gaining traction with promises of impressively low latency, high bandwidth, and global reach. However, the research community knows relatively little about their operation and performance in practice. The obscurity is largely due to the high barrier of entry for measuring LEO networks, which requires

Downlink Cooperative MIMO in LEO Satellites [PDF]
IEEE Access, 2020 We consider a communication scheme in which two low earth orbit (LEO) satellites jointly transmit (at the same time and frequency) to a multi antenna land terminal (LT). This scheme can increase the achievable terminal throughput by up to a factor of 2, depending on the channel matrices.
