Journal ArticleDOI
Maximum Distance Separable Convolutional Codes
TL;DR: The main result of the paper shows that this upper bound for the free distance generalizing the Singleton bound can be achieved in all cases if one allows sufficiently many field elements.
Journal ArticleDOI
Strongly-MDS convolutional codes
TL;DR: A class of MDS convolutional codes is introduced whose column distances reach the generalized Singleton bound at the earliest possible instant, called strongly-MDS convolutionsal codes.
Journal ArticleDOI
LDPC Codes for Compressed Sensing
TL;DR: It is shown that parity-check matrices of “ good” channel codes can be used as provably “good” measurement matrices under basis pursuit and the first deterministic construction of compressed sensing measurementMatrices with an order-optimal number of rows using high-girth low-density parity- check codes constructed by Gallager is provided.
Journal ArticleDOI
Deriving Good LDPC Convolutional Codes from LDPC Block Codes
TL;DR: In this paper, several graph-cover-based methods for deriving families of time-invariant and time-varying LDPC convolutional codes from LDPC block codes are discussed.
Journal ArticleDOI
Quasi-Cyclic LDPC Codes: Influence of Proto- and Tanner-Graph Structure on Minimum Hamming Distance Upper Bounds
TL;DR: In this article, the minimum Hamming distance of low-density parity-check (LDPC) codes was shown to depend on graph structure parameters of the Tanner graph and of the underlying proto-graph.
