Error Floor Analysis of LT Codes over the Additive White Gaussian Noise Channel
, 2011 We investigate the error floor performance of Luby Transform (LT) codes over the additive white Gaussian noise channel. We first derive a lower bound on the bit error rate for an LT code, which we subsequently use to show that the corresponding error ...

Hybrid Blended WiFi Fingerprint Indoor Localization Using Multi-Task Learning and Feature-Space WKNN
Applied SciencesWiFi fingerprinting remains attractive for indoor localization because it reuses existing wireless infrastructure, yet RSSI fingerprints are high-dimensional, sparse, and often ambiguous across adjacent floors and building regions.

Performance Evaluation of Parallel Concatenated Chaos Coded Modulations
Journal of Communications Software and Systems, 2008 In this article we study the performance of a class of parallel concatenated encoders similar to a turbo trellis coded modulation, but where the constituent encoders are chaos coded modulators.

Superconvergence and error estimation of finite element solutions to fire-exposed frame problems
, 2000 This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.When a fire reaches the point of flashover the hot gases inside the burning room ignite resulting in furnace-like conditions.

A Sub-Graph Expansion-Contraction Method for Error Floor Computation
, 2020 In this paper, we present a computationally efficient method for estimating error floors of low-density parity-check (LDPC) codes over the binary symmetric channel (BSC) without any prior knowledge of its trapping sets (TSs).

Advanced Materials, EarlyView.A general, versatile laser‐shock synthesis process is reported to produce various bimetallic CuNi, CuFe, CuCo, and medium‐entropy CuFeCoNi heterostructures, in which crystalline metal nanoparticles are anchored to amorphous hydroxide supports. During nitrate reduction reaction, the heterostructures undergo dynamic amorphous/crystalline reconstruction ...
