A Cutting Plane Method based on Redundant Rows for Improving Fractional Distance
Makoto Miwa, Tadashi Wadayama, Ichi Takumi
In this paper, an idea of the cutting plane method is employed to improve the fractional distance of a given binary parity check matrix. The fractional distance is the minimum weig…
Asymptotic Concentration Behaviors of Linear Combinations of Weight Distributions on Random Linear Code Ensemble
Tadashi Wadayama
Asymptotic concentration behaviors of linear combinations of weight distributions on the random linear code ensemble are presented. Many important properties of a binary linear cod…
Gradient Descent Bit Flipping Algorithms for Decoding LDPC Codes
Tadashi Wadayama, Keisuke Nakamura, Masayuki Yagita +3
A novel class of bit-flipping (BF) algorithms for decoding low-density parity-check (LDPC) codes is presented. The proposed algorithms, which are called gradient descent bit flippi…
On Undetected Error Probability of Binary Matrix Ensembles
Tadashi Wadayama
In this paper, an analysis of the undetected error probability of ensembles of binary matrices is presented. The ensemble called the Bernoulli ensemble whose members are considered…
