Coherence optimised subarray partition for hybrid MIMO phased array radar

open access: yesIET Microwaves, Antennas & Propagation, 2021
Hybrid MIMO phased array radar (HMPAR) is widely recognized in the research of radar systems owing to its capacity to provide a balance or trade‐off between transmit coherent gain and waveform diversity gain.

Speeding Up Distributed Machine Learning Using Codes [PDF]

open access: yesIEEE Transactions on Information Theory, 2015
Codes are widely used in many engineering applications to offer robustness against noise. In large-scale systems, there are several types of noise that can affect the performance of distributed machine learning algorithms—straggler nodes, system failures,

Wind energy systems application to regional utilities. [SERIES code; WINDS code; PHASES code; AVERAGE code; NETLOAD code; GENSYS code; PROCOST code; CAP6 code; EVEN code] [PDF]

open access: yes, 1979
A methodology for analyzing the economic impact of WECS on a utility is described in Volume I of this report. The methodology requires extrapolating both historical utility load data and historical wind power into a year of analysis; calculating the total amount of funds made available in that year, as a result of the inclusion of wind power in the ...

Multishot Codes for Network Coding Using Rank-Metric Codes [PDF]

open access: yes2010 Third IEEE International Workshop on Wireless Network Coding, 2010
The multiplicative-additive finite-field matrix channel arises as an adequate model for linear network coding systems when links are subject to errors and erasures, and both the network topology and the network code are unknown. In a previous work we proposed a general construction of multishot codes for this channel based on the multilevel coding ...

Frameproof codes, separable codes and $$B_2$$ codes: Bounds and constructions

open access: yesCryptography and Communications, 2023
AbstractIn this paper, constructions of frameproof codes, separable codes, and $$B_2$$ B 2 codes are obtained. For each family of codes, the Lovász Local Lemmais used to establish lower bounds for the codes.

A generalized SEIRW-VN framework for modeling infectious disease dynamics

open access: yesScientific Reports
Understanding how infectious diseases spread requires models that integrate both human contact structure and environmental factors. We propose SEIRW-VN, a generalized epidemic framework that combines network heterogeneity, indirect transmission via ...

Spatially-Coupled MacKay-Neal Codes and Hsu-Anastasopoulos Codes

open access: yes, 2011
Kudekar et al. recently proved that for transmission over the binary erasure channel (BEC), spatial coupling of LDPC codes increases the BP threshold of the coupled ensemble to the MAP threshold of the underlying LDPC codes.
