The Snowflake Decoding Algorithm
This paper describes an automated algorithm for generating a group code using any unitary group, initial vector, and generating set that satisfy a necessary condition. Examples with exceptional complex reflection groups, as well as an analysis of the decoding complexity, are also included. Extending these examples, group codes based on wreath products of complex matrix groups are constructed. E...
متن کاملSearch Based Weighted Multi-Bit Flipping Algorithm for High-Performance Low-Complexity Decoding of LDPC Codes
In this paper, two new hybrid algorithms are proposed for decoding Low Density Parity Check (LDPC) codes. Original version of the proposed algorithms named Search Based Weighted Multi Bit Flipping (SWMBF). The main idea of these algorithms is flipping variable multi bits in each iteration, change in which leads to the syndrome vector with least hamming weight. To achieve this, the proposed algo...

متن کاملDesigning a Stochastic Multi-Product Closed Loop Supply Chain Network Considering the Discount and Solving Using the Firefly Algorithm with Decoding Based on Priority
The closed loop supply chain is becoming one of the industry's most important areas of business, due to environmental and business factors. Planning and implementing a closed loop supply chain network provide more profit, customer satisfaction, and a good social image to the company. While most supply chain networks are not equipped with back-up channels, this paper presents a mixed integer non...
متن کاملA Novel Patch-Based Digital Signature
In this paper a new patch-based digital signature (DS) is proposed. The proposed approach similar to steganography methods hides the secure message in a host image. However, it uses a patch-based key to encode/decode the data like cryptography approaches. Both the host image and key patches are randomly initialized. The proposed approach consists of encoding and decoding algorithms. The encodin...
