Toeplitz Hash Algorithm

We propose joint spatial division and multiplexing (JSDM), an approach to multiuser MIMO downlink that exploits the structure of… (More)

Compressed sensing (CS) has recently emerged as a powerful signal acquisition paradigm. In essence, CS enables the recovery of… (More)

The nuclear norm (sum of singular values) of a matrix is often used in convex heuristics for rank minimization problems in… (More)

This article describes a very different approach to the decentralized compression of networked data. Considering a particularly… (More)

The problem of recovering a sparse signal x Rn from a relatively small number of its observations of the form y = Ax Rk, where A… (More)

In Part I, we found a closed-form expression for the expected complexity of the sphere-decoding algorithm, both for the infinite… (More)

Blur removal is an important problem in signal and image processing. The blurring matrices obtained by using the zero boundary… (More)

We consider a digital signal processing sensor array system, based on randomly distributed sensor nodes, for surveillance and… (More)

We consider least-squares problems where the coefficient matrices A, b are unknown but bounded. We minimize the worst-case… (More)

The concept of a white Gaussian noise (WGN) innovations process has been used in a number of detection and estimation problems… (More)
