Cross-Layer Optimal Rate Allocation for Heterogeneous Wireless Multicast
EURASIP Journal on Wireless Communications and Networking, 2009 Heterogeneous multicast is an efficient communication scheme especially for multimedia applications running over multihop networks. The term heterogeneous refers to the phenomenon when multicast receivers in the same session require service at different ...

High Performance Short Polar Codes: A Concatenation Scheme Using Spinal Codes as the Outer Code
IEEE Access, 2018 An innovative scheme for concatenating the polar codes with the recently proposed spinal codes is presented in this paper. The primary objective is to improve the performance of the polar codes in the finite-length regime.

Resource allocation, hyperphagia and compensatory growth [PDF]
, 2004 Organisms often shown enhanced growth during recovery from starvation, and can even overtake continuously fed conspecifics (overcompensation). In an earlier paper (Ecology 84, 2777-2787), we studied the relative role played by hyperphagia and resource ...

Generalized geometric programming for rate allocation in consensus [PDF]
2017 55th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2017 Distributed averaging, or distributed average consensus, is a common method for computing the sample mean of the data dispersed among the nodes of a network in a decentralized manner. By iteratively exchanging messages with neighbors, the nodes of the network can converge to an agreement on the sample mean of their initial states.

Resource Allocation for Multicarrier Rate-Splitting Multiple Access System
IEEE Access, 2020 In this article, we investigate the resource allocation problem for the multicarrier rate-splitting multiple access (RSMA) systems. On each subcarrier, messages are non-orthogonal superimposed on the power domain through the one-layer RSMA scheme.

Distributed Storage Allocations for Optimal Service Rates [PDF]
IEEE Transactions on Communications, 2021 Redundant storage maintains the performance of distributed systems under various forms of uncertainty. This paper considers the uncertainty in node access and download service. We consider two access models under two download service models. In one access model, a user can access each node with a fixed probability, and in the other, a user can access a

Joint Coding and Adaptive Image Transmission Scheme Based on DP-LDPC Codes for IoT Scenarios
IEEE Access, 2019 For wireless image communication in the Internet of Things (IoT) scenarios, fast and low error coding and transmission mechanisms are imperative. The joint source-channel coding scheme based on the double protograph low-density parity-check (DP-LDPC ...

Popularity-aware rate allocation in multiview video [PDF]
SPIE Proceedings, 2010 We propose a framework for popularity-driven rate allocation in H.264/MVC-based multi-view video communications when the overall rate and the rate necessary for decoding each view are constrained in the delivery architecture. We formulate a rate allocation optimization problem that takes into account the popularity of each view among the client ...
