IEEE Access, 2019 In practical applications of electromagnetic measurement while drilling (EM-MWD) in the underground coal mine, the signal-to-noise ratio (SNR) of a receiver cannot always meet the requirements of reliable communication conditions due to the earth ...

Performance of FSO-OFDM based on BCH code
MATEC Web of Conferences, 2016 As contrasted with the traditional OOK (on-off key) system, FSO-OFDM system can resist the atmospheric scattering and improve the spectrum utilization rate effectively.

On Quantum and Classical BCH Codes [PDF]
IEEE Transactions on Information Theory, 2007 Classical BCH codes that contain their (Euclidean or Hermitian) dual codes can be used to construct quantum stabilizer codes; this correspondence studies the properties of such codes. It is shown that a BCH code of length n can contain its dual code only if its designed distance d=O(sqrt(n)), and the converse is proved in the case of narrow-sense codes.

Reverse Concatenated Coded Modulation for High-Speed Optical Communication
IEEE Photonics Journal, 2010 We propose the reverse concatenated code as a forward error correction (FEC) scheme suitable for beyond 100-Gb/s optical transmission. In this scheme, BCH code is used as inner code and low-density parity-check (LDPC) code as outer code.

Information and Control, 1979 A new class of error-correcting codes, which generalizes the BCH codes and the polynomial codes of Goethals is constructed. These new codes have associated designed distances, which give lower bounds for their error-correcting capability. We also give a new construction of orthogonal idempotents, and hence of minimal ideals, in any semisimple ...

Educational pathways and outcomes for care‐experienced children: A 16‐year longitudinal study
British Educational Research Journal, EarlyView.Abstract Children who are removed from their birth families during childhood—termed care‐experienced—can be at risk for lower educational attainment and poorer school experiences, often linked to deprivation and behavioural factors. However, research often uses aggregated measures that obscure the complexities of care (e.g.

British Educational Research Journal, EarlyView.Abstract Teacher retention is often explained through workload, job satisfaction and burnout, but these accounts have examined less systematically whether teachers experience their profession as socially and institutionally recognised. Drawing on recognition theory, this study examines how occupational recognition is configured across material and ...

LDPC Error Floor Improvement [PDF]
Engineering and Technology Journal, 2012 The error-correcting performance of low-density parity check (LDPC) codes, when decoded using practical iterative decoding algorithms, is known to be close to Shannon limits.

A Family of Reversible BCH Codes
CoRR, 2016 Cyclic codes are an interesting class of linear codes due to their efficient encoding and decoding algorithms as well as their theoretical importance. BCH codes form a subclass of cyclic codes and are very important in both theory and practice as they have good error-correcting capability and are widely used in communication systems, storage devices ...

Harnessing Diversity: Majority‐Group Acculturation Predicts Creativity and Flourishing Over Time
European Journal of Social Psychology, EarlyView.ABSTRACT Creativity and flourishing are core aims of higher education (HE) institutions and government initiatives globally. Large‐scale projects have linked creativity and flourishing with cultural diversity, yet their associations with majority‐group acculturation (i.e., how members of dominant culture groups adopt minority‐cultural elements and/or ...
