Dynamic rate and channel use allocation for cooperative wireless networks

EURASIP 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.

Deep Learning-Based Resource Allocation Scheme for Heterogeneous NOMA Networks

IEEE Access, 2023
In this paper, we consider downlink power-domain non-orthogonal multiple access (NOMA) in heterogeneous networks (HetNets) and propose resource allocation algorithms for subchannels and transmit powers to improve the sum rate performance while satisfying

ROBUST IMAGE TRANSMISSION USING SPIHT AND TURBO- CODES

Electrica, 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.

A resource allocation algorithm based on double slots

Dianxin kexue, 2016
A resource allocation algorithm based on double slots was proposed to minimize the transmitting power in wireless communications.Being aware of the channel difference between the two adjacent slots,the second slot was allocated in advance partial of the ...

Biometric Quantization through Detection Rate Optimized Bit Allocation

EURASIP Journal on Advances in Signal Processing, 2009
Extracting binary strings from real-valued biometric templates is a fundamental step in many biometric template protection systems, such as fuzzy commitment, fuzzy extractor, secure sketch, and helper data systems.

Allocation Rules and Their Error Rates

Journal 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.

Measurable Residual Disease Monitoring During Treatment for Pediatric Acute Myeloid Leukemia in First Relapse

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survival after relapse in pediatric acute myeloid leukemia (AML) remains poor, highlighting the critical importance of identifying prognostic factors to guide optimal relapse management. Methods We investigated the prognostic impact of multiparameter flow cytometry (MFC) measurable residual disease (MRD) in 188 patients with first ...

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

IET 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.
