Quantized Compressive Sensing
Wei Dai, Hoa Vinh Pham, Olgica Milenkovic
We study the average distortion introduced by scalar, vector, and entropy coded quantization of compressive sensing (CS) measurements. The asymptotic behavior of the underlying qua…

Weighted Superimposed Codes and Constrained Integer Compressed Sensing
Wei Dai, Olgica Milenkovic
We introduce a new family of codes, termed weighted superimposed codes (WSCs). This family generalizes the class of Euclidean superimposed codes (ESCs), used in multiuser identific…

Joint Beamforming for Multiaccess MIMO Systems with Finite Rate Feedback
Wei Dai, Brian C. Rider, Youjian Liu
This paper considers multiaccess multiple-input multiple-output (MIMO) systems with finite rate feedback. The goal is to understand how to efficiently employ the given finite feedb…
