Backing off from Infinity: Performance Bounds via Concentration of Spectral Measure for Random MIMO Channels
Yuxin Chen, Andrea J. Goldsmith, Yonina C. Eldar
The performance analysis of random vector channels, particularly multiple-input-multiple-output (MIMO) channels, has largely been established in the asymptotic regime of large chan…
An Algorithm for Exact Super-resolution and Phase Retrieval
Yuxin Chen, Yonina C. Eldar, Andrea J. Goldsmith
We explore a fundamental problem of super-resolving a signal of interest from a few measurements of its low-pass magnitudes. We propose a 2-stage tractable algorithm that, in the a…
Exact and Stable Covariance Estimation from Quadratic Sampling via Convex Programming
Yuxin Chen, Yuejie Chi, Andrea Goldsmith
Statistical inference and information processing of high-dimensional data often require efficient and accurate estimation of their second-order statistics. With rapidly changing da…
Spectral Compressed Sensing via Structured Matrix Completion
Yuxin Chen, Yuejie Chi
The paper studies the problem of recovering a spectrally sparse object from a small number of time domain samples. Specifically, the object of interest with ambient dimension i…
Robust Spectral Compressed Sensing via Structured Matrix Completion
Yuxin Chen, Yuejie Chi
The paper explores the problem of \emph{spectral compressed sensing}, which aims to recover a spectrally sparse signal from a small random subset of its time domain samples. Th…
On the Minimax Capacity Loss under Sub-Nyquist Universal Sampling
Yuxin Chen, Andrea Goldsmith, Yonina C. Eldar
This paper investigates the information rate loss in analog channels when the sampler is designed to operate independent of the instantaneous channel occupancy. Specifically, a mul…
