Principles of Physical Layer Security in Multiuser Wireless Networks: A Survey
Amitav Mukherjee, S. A. A. Fakoorian, Jing Huang +1
This paper provides a comprehensive review of the domain of physical layer security in multiuser wireless networks. The essential premise of physical-layer security is to enable th…
Windowed Decoding of Protograph-based LDPC Convolutional Codes over Erasure Channels
Aravind Iyengar, Marco Papaleo, Paul Siegel +3
We consider a windowed decoding scheme for LDPC convolutional codes that is based on the belief-propagation (BP) algorithm. We discuss the advantages of this decoding scheme and id…
The Re-Encoding Transformation in Algebraic List-Decoding of Reed-Solomon Codes
Ralf Koetter, Jun Ma, Alexander Vardy
The main computational steps in algebraic soft-decoding, as well as Sudan-type list-decoding, of Reed-Solomon codes are bivariate polynomial interpolation and factorization. We int…
Circulant Arrays on Cyclic Subgroups of Finite Fields: Rank Analysis and Construction of Quasi-Cyclic LDPC Codes
Li Zhang, Shu Lin, Khaled Abdel-Ghaffar +2
This paper consists of three parts. The first part presents a large class of new binary quasi-cyclic (QC)-LDPC codes with girth of at least 6 whose parity-check matrices are constr…
Threshold Saturation via Spatial Coupling: Why Convolutional LDPC Ensembles Perform so well over the BEC
Shrinivas Kudekar, Tom Richardson, Ruediger Urbanke
Convolutional LDPC ensembles, introduced by Felstrom and Zigangirov, have excellent thresholds and these thresholds are rapidly increasing as a function of the average degree. Seve…
