LDPC Codes for Compressed Sensing
Alexandros G. Dimakis, Roxana Smarandache, Pascal O. Vontobel
We present a mathematical connection between channel coding and compressed sensing. In particular, we link, on the one hand, \emph{channel coding linear programming decoding (CC-LP…
Quasi-Cyclic Asymptotically Regular LDPC Codes
David G. M. Mitchell, Roxana Smarandache, Michael Lentmaier +1
Families of "asymptotically regular" LDPC block code ensembles can be formed by terminating (J,K)-regular protograph-based LDPC convolutional codes. By varying the termination leng…
Decoding of Convolutional Codes over the Erasure Channel
Virtudes Tomás, Joachim Rosenthal, Roxana Smarandache
In this paper we study the decoding capabilities of convolutional codes over the erasure channel. Of special interest will be maximum distance profile (MDP) convolutional codes. Th…
Deriving Good LDPC Convolutional Codes from LDPC Block Codes
Ali E. Pusane, Roxana Smarandache, Pascal O. Vontobel +1
Low-density parity-check (LDPC) convolutional codes are capable of achieving excellent performance with low encoding and decoding complexity. In this paper we discuss several graph…
