Space-Time Correlation Properties of a 3D Two-Sphere Model for Non-Isotropic MIMO Mobile-to-Mobile Channels
This paper proposes a novel three-dimensional (3D) two-sphere regular-shaped geometry-based stochastic model (RSGBSM) with only double-bounced rays for non-isotropic scattering nar...

Scheduling for small delay in multi-rate multi-channel wireless networks
—This paper considers the problem of designing scheduling algorithms for multi-channel (e.g., OFDM-based) wireless downlink systems. We show that the Server-Side Greedy (SSG) rul...

Reconstructing the indirect light field for global illumination
Stochastic techniques for rendering indirect illumination suffer from noise due to the variance in the integrand. In this paper, we describe a general reconstruction technique tha...

The early bird gets the buzz: detecting anomalies and emerging trends in information networks
In this work we propose a novel approach to anomaly detection in streaming communication data. We first build a stochastic model for the system based on temporal communication pa...
