Generalized concatenated quantum codes [PDF]
Physical Review A, 2009 We introduce the concept of generalized concatenated quantum codes. This generalized concatenation method provides a systematical way for constructing good quantum codes, both stabilizer codes and nonadditive codes. Using this method, we construct families of new single-error-correcting nonadditive quantum codes, in both binary and nonbinary cases ...

Spatially coupled serially concatenated codes via parity re‐encoding
Electronics Letters, 2021 The recently introduced spatially coupled turbo‐like codes are attractive in trading‐off performances between the error‐floor region and the water‐fall region.

A Unified Ensemble of Concatenated Convolutional Codes [PDF]
, 2017 We introduce a unified ensemble for turbo-like codes (TCs) that contains the four main classes of TCs: parallel concatenated codes, serially concatenated codes, hybrid concatenated codes, and braided convolutional codes.

Concatenated codes: serial and parallel [PDF]
IEEE International Symposium on Information Theory, 2003. Proceedings., 2003 An analogy is examined between serially concatenated codes and parallel concatenations whose interleavers are described by bipartite graphs with good expanding properties. In particular, a modified expander code construction is shown to behave very much like Forney's classical concatenated codes, though with improved decoding complexity.

Code-Based Cryptography With Generalized Concatenated Codes for Restricted Error Values
IEEE Open Journal of the Communications Society, 2022 Code-based cryptosystems are promising candidates for post-quantum cryptography. Recently, generalized concatenated codes over Gaussian and Eisenstein integers were proposed for those systems. For a channel model with errors of restricted weight, those q-

IEEE Access, 2019 Most multimedia source encoders produce scalable bit streams that are vulnerable to noisy channel effects. Unequal error protection (UEP) designs are attractive solutions for such scalable bit streams.

Exact Performance of Concatenated Quantum Codes [PDF]
, 2002 When a logical qubit is protected using a quantum error-correcting code, the net effect of coding, decoherence (a physical channel acting on qubits in the codeword) and recovery can be represented exactly by an effective channel acting directly on the ...

A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes
Dianxin kexue, 2021 Polar codes have perfect coding and decoding performance as a kind of error correction code, which have become a standard coding scheme for 5G short code control channel. While the length of polar codes is short, its performance is not good enough.

Generalized concatenation for quantum codes [PDF]
2009 IEEE International Symposium on Information Theory, 2009 We show how good quantum error-correcting codes can be constructed using generalized concatenation. The inner codes are quantum codes, the outer codes can be linear or nonlinear classical codes. Many new good codes are found, including both stabilizer codes as well as so-called nonadditive codes.
