Caching Yields up to 5x Spectral Efficiency in Multi-Beam Satellite Communications
Hui Zhao, Dirk Slock, Petros Elia
This paper examines the integration of vector coded caching (VCC) into multi-beam satellite communications (SATCOM) systems and demonstrates that even limited receiver-side caching…
Models, Methods and Waveforms for Estimation and Prediction of Doubly Sparse Time-Varying Channels
Wissal Benzine, Ali Bemani, Nassar Ksairi +1
This paper investigates channel estimation for linear time-varying (LTV) wireless channels under double sparsity, i.e., sparsity in both the delay and Doppler domains. An on-grid a…
Affine Frequency Division Multiplexing for Compressed Sensing of Time-Varying Channels
Wissal Benzine, Ali Bemani, Nassar Ksairi +1
This paper addresses compressed sensing of linear time-varying (LTV) wireless propagation links under the assumption of double sparsity i.e., sparsity in both the delay and Doppler…
Matched-filter Precoded Rate Splitting Multiple Access: A Simple and Energy-efficient Design
Hui Zhao, Dirk Slock
We introduce an energy-efficient downlink rate splitting multiple access (RSMA) scheme, employing a simple matched filter (MF) for precoding. We consider a transmitter equipped wit…
Exact SINR Analysis of Matched-filter Precoder
Hui Zhao, Dirk Slock, Petros Elia
This paper answers a fundamental question about the exact distribution of the signal-to-interference-plus-noise ratio (SINR) under matched-filter (MF) precoding. Specifically, we d…
