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…
Measuring Dependencies of Order Statistics: An Information Theoretic Perspective
Alex Dytso, Martina Cardone, Cynthia Rush
Consider a random sample drawn independently and identically distributed from some known sampling distribution . Let $X_{(1)} \le X_{(2)} \le ... \le X_…
All-or-nothing statistical and computational phase transitions in sparse spiked matrix estimation
Jean Barbier, Nicolas Macris, Cynthia Rush
We determine statistical and computational limits for estimation of a rank-one matrix (the spike) corrupted by an additive gaussian noise matrix, in a sparse limit, where the under…
mmWave Channel Estimation via Approximate Message Passing with Side Information
Dror Baron, Cynthia Rush, Yavuz Yapici
This work considers millimeter-wave channel estimation in a setting where parameters of the underlying mmWave channels are varying dynamically over time and there is a single drift…
Rigorous State Evolution Analysis for Approximate Message Passing with Side Information
Hangjin Liu, Cynthia Rush, Dror Baron
A common goal in many research areas is to reconstruct an unknown signal x from noisy linear measurements. Approximate message passing (AMP) is a class of low-complexity algorithms…
Capacity-achieving Spatially Coupled Sparse Superposition Codes with AMP Decoding
Cynthia Rush, Kuan Hsieh, Ramji Venkataramanan
Sparse superposition codes, also called sparse regression codes (SPARCs), are a class of codes for efficient communication over the AWGN channel at rates approaching the channel ca…
