In this paper, we propose a framework for integrated stereo synthetic aperture radar (SAR) sensing and cooperative communication in low Earth orbit (LEO) satellite constellations. To facilitate multi-satellite cooperation under the severe Doppler dynamics of LEO channels, a unified orthogonal delay-Doppler division mul...

To achieve ubiquitous global coverage, low Earth orbit (LEO) satellite Internet of Things (IoT) constellations increasingly rely on multi-layer orbital architectures. However, characterizing their performance under practical Rician channels faces a significant challenge due to inherent analytical intractability. In thi...

Random multiplexing (RM) with approximate message passing (AMP)-type detectors effectively address doubly-selective fading in high-mobility scenarios while achieving maximum a posteriori (MAP) bit-error rate performance. To further improve RM performance, this paper considers oversampling at an integer multiple of the...
