Exploiting Self-Similarity for Under-Determined MIMO Modulation Recognition

2020

Modulation recognition (modrec) is an essential functional component of future wireless networks with critical applications in dynamic spectrum access. While predominantly studied in single-input single-output (SISO) systems, practical modrec for multiple-input multiple-output (MIMO) communications requires …

Low Rank Multi-Dictionary Selection at Scale

2024 · arXiv (Cornell University)

The sparse dictionary coding framework represents signals as a linear combination of a few predefined dictionary atoms. It has been employed for images, time series, graph signals and recently for 2-way (or 2D) spatio-temporal data …
