A unified framework is given for multiple user information networks. These networks consist of several users communicating to one another in the preaence of arbitrary inteflerence and noise. The prese...
Decision noise:An explanation for observed violations of signal detection theory
Decision noise observed violations signal detection theory
2015/7/28
In signal detection theory (SDT), responses are governed by perceptual noise and a flexible decision criterion. Recent criticisms of SDT (see, eg, Balakrishnan, 1999) have identified violations of its...

This paper develops a mathematical theory of super-resolution. Broadly speaking, superresolution is the problem of recovering the fine details of an object—the high end of its spectrum— from coarse sc...

Phase Retrieval Wirtinger Flow Theory Algorithms
2015/6/17
We study the problem of recovering the phase from magnitude measurements; specifically, we wish to reconstruct a complex-valued signal x ∈ Cn about which we have phaseless samples of the form yr = ∣&#...
