A Hybrid Approach to Coded Compressed Sensing where Coupling Takes Place via the Outer Code
Jamison R. Ebert, Vamsi K. Amalladinne, Jean-Francois Chamberland +1
This article seeks to advance coded compressed sensing (CCS) as a practical scheme for unsourced random access. The original CCS algorithm features a concatenated structure where a…
Unsourced Random Access with Coded Compressed Sensing: Integrating AMP and Belief Propagation
Vamsi K. Amalladinne, Asit Kumar Pradhan, Cynthia Rush +2
Sparse regression codes with approximate message passing (AMP) decoding have gained much attention in recent times. The concepts underlying this coding scheme extend to unsourced r…
Two-Stage Adaptive Pooling with RT-qPCR for COVID-19 Screening
Anoosheh Heidarzadeh, Krishna R. Narayanan
We propose two-stage adaptive pooling schemes, 2-STAP and 2-STAMP, for detecting COVID-19 using real-time reverse transcription quantitative polymerase chain reaction (RT-qPCR) tes…
On Accelerated Testing for COVID-19 Using Group Testing
Krishna R. Narayanan, Anoosheh Heidarzadeh, Ramanan Laxminarayan
COVID-19 has resulted in a global health crisis that may become even more acute over the upcoming months. One of the main reasons behind the current rapid growth of COVID-19 in the…
