The weight distribution and randomness of linear codes [PDF]
Finding the weight distributions of block codes is a problem of theoretical and practical interest. Yet the weight distributions of most block codes are still unknown except for a few classes of block codes.

Code diversity in multiple antenna wireless communication
, 2008 The standard approach to the design of individual space-time codes is based on optimizing diversity and coding gains. This geometric approach leads to remarkable examples, such as perfect space-time block codes, for which the complexity of Maximum ...

Multi-Block Interleaved Codes for Local and Global Read Access [PDF]
arXiv, 2017 We define multi-block interleaved codes as codes that allow reading information from either a small sub-block or from a larger full block. The former offers faster access, while the latter provides better reliability. We specify the correction capability of the sub-block code through its gap $t$ from optimal minimum distance, and look to have full ...

Soft-decision decoding of some block codes [PDF]
The performance of certain binary block codes with soft-decision decoding is evaluated by simulation. A construction is proposed to introduce memory on block codes, and simulation results are shown for a trellis code derived from the Nordstrom-Robinson ...

Coordinated Multicasting with Opportunistic User Selection in Multicell Wireless Systems
, 2015 Physical layer multicasting with opportunistic user selection (OUS) is examined for multicell multi-antenna wireless systems. By adopting a two-layer encoding scheme, a rate-adaptive channel code is applied in each fading block to enable successful ...

Efficient LDPC Code Design based on Genetic Algorithm for IoT Applications
EAI Endorsed Transactions on Industrial Networks and Intelligent SystemsIn this paper, we propose a low-density parity check (LDPC) code design scheme that improves the performance of the existing genetic algorithm-based LDPC scheme. In particular, we enhance the performance of the LDPC code by removing the girth-4 property

Optimal Space-Time Block Code Designs Based on Irreducible Polynomials of Degree Two [PDF]
arXiv, 2019 The main of this paper is to prove that in terms of normalized density, a space-time block code based on an irreducible quadratic polynomial over the Eisenstein integers is an optimal space-time block code compared with any quadratic space-time block code over the ring of integers of imaginary quadratic fields. In addition we find the optimal design of

Spatially Coupled Codes with Sub-Block Locality: Joint Finite Length-Asymptotic Design Approach [PDF]
arXiv, 2020 SC-LDPC codes with sub-block locality can be decoded locally at the level of sub-blocks that are much smaller than the full code block, thus providing fast access to the coded information. The same code can also be decoded globally using the entire code block, for increased data reliability.
