Experimental characterization of a 400  Gbit/s orbital angular momentum multiplexed free-space optical link over 120 m [PDF]

open access: yes, 2016
We experimentally demonstrate and characterize the performance of a 400-Gbit/s orbital angular momentum (OAM) multiplexed free-space optical link over 120- meters on the roof of a building.

Precipitation Forecast Correction in South China Based on SVD and Machine Learning

open access: yes应用气象学报, 2022
Precipitation can be induced by various weather systems and a series of complex physical processes, so its prediction is relatively difficult in weather forecasting. Due to the limitation of numerical model, the prediction error is inevitable.

Comparing Forward-Error Correction and DNS [PDF]

open access: yes, 2018
Many statisticians would agree that, had it not been for web browsers, the development of sim- ulated annealing might never have occurred. Given the trends in relational technology, analysts predictably note the synthesis of multi-processors. We describe

Inverse Solution Error Analysis and Correction of Beam Steering System Based on Risley Prisms

open access: yesApplied Sciences, 2022
The pointing accuracy of the Risley prisms beam-steering system mainly depends on the accuracy of the solution method and the impact of the error on the solution.

A Case for Forward-Error Correction [PDF]

open access: yes, 2018
Unified classical symmetries have led to many typical advances, including gigabit switches and Markov models. After years of appropriate research into flip-flop gates, we show the development of information retrieval systems, which embodies the robust ...

General theory for decoy-state quantum key distribution with arbitrary number of intensities

open access: yes, 2007
We develop a general theory for quantum key distribution (QKD) in both the forward error correction and the reverse error correction cases when the QKD system is equipped with phase-randomized coherent light with arbitrary number of decoy intensities ...

Reed-solomon forward error correction (FEC) schemes, RFC 5510 [PDF]

open access: yes, 2009
This document describes a Fully-Specified Forward Error Correction (FEC) Scheme for the Reed-Solomon FEC codes over GF(2^^m), where m is in {2..16}, and its application to the reliable delivery of data objects on the packet erasure channel (i.e., a ...

Noise suppression using optimum filtering of OCs generated by a multiport encoder/decoder [PDF]

open access: yes, 2012
We propose a novel receiver configuration using an extreme narrow band-optical band pass filter (ENB-OBPF) to reduce the multiple access interference (MAI) and beat noises in an optical code division multiplexing (OCDM) transmission.

A Low-Complexity Diversity-Preserving Universal Bit-Flipping Enhanced Hard Decision Decoder for Arbitrary Linear Codes

open access: yesIEEE Open Journal of Vehicular Technology
V2X (Vehicle-to-everything) communication relies on short messages for short-range transmissions over a fading wireless channel, yet requires high reliability and low latency. Hard-decision decoding sacrifices the preservation of diversity order, leading

Joint Decision-Directed Channel and Noise-Variance Estimation for MIMO OFDM/SDMA Systems Based on Expectation-Conditional Maximization [PDF]

open access: yes, 2011
A joint channel impulse response (CIR) and noise-variance estimation scheme is proposed for multiuser multiple-input–multiple-output (MIMO) orthogonal frequency-division multiplexing/space-division multiple access (OFDM/SDMA) systems, which is based on ...
