Information technology Pseudocodewords of Parity-Check Codes CLEMSON UNIVERSITY Gretchen L. Matthews KositwattanarerkWittawatThe success of modern algorithms for the decoding problem such as message-passing iterative decoding and linear programming decoding lies in their local nature. This feature allows ...
Propose a construction method to construct codes capable of correcting k asymmetric errors, for k > 1. 2. Designing algorithms for efficient encoding/decoding of the proposed codes. 54 3. Using the new partitioning algorithm to find better A-partition for some other values of p. The A-...
Note that no effort has been made to `optimize' most of the algorithms used in the programs below. The algorithms work well, but by no means should be used as a basis for an implementation. All these programs are free to use for academic and personal purposes only. Use them at your ow...
We provide an example of using the framework to generate the first shift Gray codes for weak orders in constant amortized time per string, where consecutive strings differ by a shift or a symbol change. Recently, Sawada and Wong [17] and also Jacques and Wong [9] have proposed algorithms ...

We now give a pseudocode description of a modified sweep decoder that works for 3D toric codes defined on lattices with boundaries. We note that all addition below is carried out modulo 2, as we view errors and syndromes as \({\mathbb {F}}_2\) vectors. The decoder can fail in two ...
In order to make our presentation more intuitive, instead of specifying the next message function CompNext(Π), we specify the pseudocode for the doNext(x) instruction of the compiled machine. We note that CompNext(Π) is implicitly defined by this description. TLR-RAM takes as input an ...
The improved penalty function can punish the pseudocodewords quickly near x=0 and x=1, and punish the pseudocodewords smoothly near x=0.5. Two LDPC codes in the IEEE 802.16e standard are simulated to show that the ADMM penalized decoding method with the improved penalty function can improve ...
FIG. 19 is a detailed flow diagram illustrating the details of the decoding process for generalized MPG codes having an MR property constructed using an arbitrary method. FIG. 20 illustrates in pseudocode an exemplary implementation of finding a minimum recovery cost in the decoding of the generaliz...
