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…
Physical-Layer Cryptography Through Massive MIMO
Thomas Dean, Andrea Goldsmith
We propose the new technique of physical-layer cryptography based on using a massive MIMO channel as a key between the sender and desired receiver, which need not be secret. The go…
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…
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…
Energy Efficient Cooperative Strategies for Relay-Assisted Downlink Cellular Systems, Part I: Theoretical Framework
Stefano Rini, Ernest Kurniawany, Levan Ghaghanidze +1
The impact of cognition on the energy efficiency of a downlink cellular system in which multiple relays assist the transmission of the base station is considered. The problem is mo…
