Design of Improved Quasi-Cyclic Protograph-Based Raptor-Like LDPC Codes for Short Block-Lengths
Sudarsan V. S. Ranganathan, Dariush Divsalar, Richard D. Wesel
Protograph-based Raptor-like low-density parity-check codes (PBRL codes) are a recently proposed family of easily encodable and decodable rate-compatible LDPC (RC-LDPC) codes. Thes…
Optimizing Transmission Lengths for Limited Feedback with Non-Binary LDPC Examples
Kasra Vakilinia, Sudarsan V. S. Ranganathan, Dariush Divsalar +1
This paper presents a general approach for optimizing the number of symbols in increments (packets of incremental redundancy) in a feedback communication system with a limited numb…
Optimality and Rate-Compatibility for Erasure-Coded Packet Transmissions when Fading Channel Diversity Increases with Packet Length
Sudarsan V. S. Ranganathan, Tong Mu, Richard D. Wesel
A message composed of packets is transmitted using erasure and channel coding over a fading channel with no feedback. For this scenario, the paper explores the trade-off between th…
On the Girth of (3,L) Quasi-Cyclic LDPC Codes based on Complete Protographs
Sudarsan V. S. Ranganathan, Dariush Divsalar, Richard D. Wesel
We consider the problem of constructing quasi-cyclic low-density parity-check (LDPC) codes from complete protographs. A complete protograph is a small bipartite graph with…
