Efficient Iterative LP Decoding of LDPC Codes with Alternating Direction Method of Multipliers

by Xiaojie Zhang, Paul H. Siegel
"... Abstract—In this paper, we propose an efficient messagepassing algorithm to solve the LP decoding problem. This algorithm is based on the alternating direction method of multipliers (ADMM), a classic technique in convex optimization theory that is designed for parallel implementation. The computatio ..."

A comparison of ARA and protograph-based LDPC block and convolutional codes

by Daniel J. Costello, Ali Emre Pusane, Christopher R. Jones, Dariush Divsalar - in Proceedings of the 2007 Information Theory and Applications Workshop
"... Abstract — ARA- and protograph-based LDPC codes are capable of achieving error performance similar to randomly constructed codes while enjoying several implementation advantages as a result of their structure. LDPC convolutional codes can be derived from these codes through an unwrapping process. In ..."

A Compact 1.1-Gb/s Encoder and a Memory-Based 600-Mb/s Decoder for LDPC Convolutional Codes

by Tyler L. Br, John C. Koob, Leendert Van Den Berg, Zhengang Chen, Student Member, Amirhossein Alimohammad, Ramkrishna Swamy, Bruce F. Cockburn, Duncan G. Elliott
"... code encoder and decoder that we implemented in a 90-nm CMOS process. The 1.1-Gb/s encoder is a compact, low-power implemen-tation that includes one-hot encoding for phase generation and built-in termination. The decoder design uses a memory-based interface with a minimum number of memory banks to d ..."

RICE UNIVERSITY Regime Change: Sampling Rate vs. Bit-Depth in Compressive Sensing

by Jason Noah Laska , 2011
"... The compressive sensing (CS) framework aims to ease the burden on analog-to-digital converters (ADCs) by exploiting inherent structure in natural and man-made signals. It has been demon-strated that structured signals can be acquired with just a small number of linear measurements, on the order of t ..."
