    Quasi-cyclic extension based on PEG algorithm for construction of LDPC codes by LEI Jing1, WANG Jian-hui1, TANG Chao-jing1

    Published 2008-01-01
    “…Several important relations between the cycle structure on the Tanner graph and the parity-check matrix H of LDPC codes were proved.A new algorithm for constructing LDPC codes was proposed that introduced quasi-cyclic ex-tension method to PEG algorithm.After a basic matrix was constructed with PEG algorithm,circulant permutation ma-trices would replace the "1"s in the basic matrix.The new method could eliminate effectively the short cycles in the basic matrix without changing the degree distribution fraction of the basic matrix.Simulations show that the quasi-cyclic extended codes based on PEG algorithm have as good error correcting performance as the LDPC codes generated by PEG algorithm in the same conditions of code length,rate,degree distribution and decoding algorithm.The conclusion of contrastive analysis is that well-chosen cycle structures can improve the decoding performance obviously under the given degree distribution.The proposed algorithm can offer a good performance and low encoding complexity synchronously by taking advantage of the quasi-cyclic code’s characteristic that its parity-check matrix H has less superposition within the cycles.…”

    LDPC-cat codes for low-overhead quantum computing in 2D by Diego Ruiz, Jérémie Guillaud, Anthony Leverrier, Mazyar Mirrahimi, Christophe Vuillot

    Published 2025-01-01
    “…Two main avenues to reduce this overhead are (i) low-density parity check (LDPC) codes requiring very few additional qubits to correct errors (ii) cat qubits where bit-flip errors are exponentially suppressed by design. …”

    Semi-random and semi-algebraic structural design for IRA-LDPC codes by Li PENG, Qi ZHANG, Bo WANG, Tao CHEN

    Published 2014-03-01
    “…A method of semi-random and semi-algebraic structure was presented for constructing the low-density parity-check matrix that corresponds to the information bits of the IRA codes.Compared with the existing structural LDPC codes,the distinct advantage of the presented compact structural array for information-bit-corresponding matrix is that the position coordinate of each 1 element in this matrix can be calculated by a determinate algebraic expression,which not only reduces the consumption of memory resource for the random parity-check matrix,but also provides the potential probability for designing low complexity hardware circuit of the LDPC encoder/decoder.In addition,compared with the existing practical LDPC codes in industrial standard,the presented IRA-LDPC code is also slight preponderance in the performance of simulation in bit error rate and signal noise ratio (BER-SNB).…”
