Improved DC-Free Run-Length Limited 4B6B Codes for Concatenated Schemes
IEEE Access, 2022 In this letter, we introduce a class of improved DC-free 4B6B codes in terms of error correction capabilities for a serially concatenated architecture. There are billions of different codebooks that can be derived from the 16 codewords contained in the ...

A nonlinear data-driven approach to bias correction of XCO2 for NASA's OCO-2 ACOS version 10 [PDF]
Atmospheric Measurement Techniques, 2023 Measurements of column-averaged dry air mole fraction of CO2 (termed XCO2) from the Orbiting Carbon Observatory-2 (OCO-2) contain systematic errors and regional-scale biases, often induced by forward model error or nonlinearity in the retrieval ...

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

Efficient performance evaluation of Forward Error Correcting codes [PDF]
2008 11th IEEE Singapore International Conference on Communication Systems, 2008 Standard Monte Carlo (SMC) simulation is employed to evaluate the performance of forward error correcting (FEC) codes. This performance is in terms of the probability of error during the transmission of information through digital communication systems.

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

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