An improved method for counting 6-cycles in low-density parity-check codes [PDF]
Since their rediscovery in the early 1990s, low-density parity-check (LDPC) codes have become the most popular error-correcting codes owing to their excellent performance. An LDPC code is a linear block code that has a sparse parity-check matrix.

On Design and Efficient Decoding of Sparse Random Linear Network Codes
While random linear network coding is known to improve network reliability and throughput, its high costs for delivering coding coefficients and decoding represent an obstacle where nodes have limited power to transmit and decode packets.

Neural computation is often traced in terms of either rate- or phase-codes. However, most circuit operations will simultaneously affect information across both coding schemes. It remains unclear how phase and rate coded information is transmitted, in the

Transformational Sparse Coding
A fundamental problem faced by object recognition systems is that objects and their features can appear in different locations, scales and orientations. Current deep learning methods attempt to achieve invariance to local translations via pooling, discarding the locations of features in the process.

Phonological codes constrain output of orthographic codes via sublexical and lexical routes in Chinese written production. [PDF]
To what extent do phonological codes constrain orthographic output in handwritten production? We investigated how phonological codes constrain the selection of orthographic codes via sublexical and lexical routes in Chinese written production ...

Neural Sparse Topical Coding [PDF]
Topic models with sparsity enhancement have been proven to be effective at learn- ing discriminative and coherent latent top- ics of short texts, which is critical to many scientific and engineering applica- tions. However, the extensions of these models require carefully tailored graphi- cal models and re-deduced inference al- gorithms, limiting their

Compressed Sensing Based Non-Orthogonal Pilot Designs for Multi-Antenna Grant-Free Access Systems
Grant-free access is an attractive approach to enable spectrum-efficient low-latency access for systems with massive number of users. Pilot design plays a crucial role for grant-free access as it needs to provide a large number of access codes with fast ...

Sparse Grassmannian Design for Noncoherent Codes via Schubert Cell Decomposition
In this paper, we propose a method for designing sparse Grassmannian codes for noncoherent multiple-input multiple-output systems. Conventional pairwise error probability formulations under uncorrelated Rayleigh fading channels fail to account for rank ...

The development of fast algorithms for key generation, encryption and decryption not only increases the efficiency of related operations. Such fast algorithms, for example, for asymmetric cryptosystems on quasi-cyclic codes, make it possible to ...
