Bayesian De-quantization and Data Compression for Low-Energy Physiological Signal Telemonitoring

Benyuan Liu, Hongqi Fan, Qiang Fu +1

We address the issue of applying quantized compressed sensing (CS) on low-energy telemonitoring. So far, few works studied this problem in applications where signals were only appr…
