A Bit-Mapping Strategy for Joint Iterative Channel Estimation and Turbo-Decoding
Abstract— In this paper, we investigate Turbo-coded transmission over a temporally correlated flat Rayleigh fading channel. Conventionally, channel estimation is performed prior...

Stochastic Resource Allocation over Fading Multiple Access and Broadcast Channels
In this paper, we consider the optimal rate and power allocation that maximizes a general utility function of average user rates in a fading multiple-access or broadcast channel. B...

Distributed cut detection in sensor networks
— We propose a distributed algorithm to detect “cuts” in sensor networks, i.e., the failure of a set of nodes that separates the networks into two or more components. The alg...

Adaptive Sum Power Iterative Waterfilling for MIMO Cognitive Radio Channels
Abstract--In this paper, the sum capacity of the Gaussian Multiple Input Multiple Output (MIMO) Cognitive Radio Channel (MCC) is expressed as a convex problem with finite number of...

Stochastic Iteration for Non-diffuse Global Illumination
This paper presents a single-pass, view-dependent method to solve the rendering equation, using a stochastic iterational scheme where the transport operator is selected randomly i...
