Dynamic rate and channel use allocation for cooperative wireless networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2023
In this paper, we investigate the performance of link adaptation (LA) algorithms for cooperative multiple access multiple relay networks. In the first transmission phase, the sources transmit in turn in consecutive time slots.

Allocation Rules and Their Error Rates

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1966
Summary The problem of choosing allocation rules and assessing their errors of mis-allocation is formulated in general terms. An inequality connecting the average apparent, the optimum, and the average actual error is established. The distributions of the actual and apparent errors are considered in some special cases.

ROBUST IMAGE TRANSMISSION USING SPIHT AND TURBO- CODES

open access: yesElectrica, 2008
This work describes a method for providing robustness to errors from a binary symmetric channel for the SPIHT image compression. The source rate and channel rate are jointly optimized by a stream of fixed-size channel packets.

Resource Allocation Techniques for Wireless Powered Communication Networks with Energy Storage Constraint [PDF]

open access: yes, 2015
This paper studies multi-user wireless powered communication networks, where energy constrained users charge their energy storages by scavenging energy of the radio frequency signals radiated from a hybrid access point (H-AP). The energy is then utilized

Secrecy rate optimization for SWIPT in two‐way relay networks with multiple untrusted relays and channel estimation errors

open access: yesIET Communications, 2021
The secrecy rate of two‐way untrusted relay networks with imperfect channel state information based on SWIPT is investigated when multiple relays harvest energy from two sources.

Optimal downlink rate allocation in multicell CDMA networks [PDF]

open access: yes, 2007
We study downlink rate allocation for a three cells CDMA system. Based on the discretized cell model, the rate optimization problem that maximizes the total downlink rate allocation is formulated.
