Turbo Detection of Symbol-Based Non-Binary LDPC-Coded Space-time Signals using Sphere Packing Modulation

, 2005
A recently proposed space-time signal construction method that combines orthogonal design with sphere packing, referred to here as (STBC-SP), has shown useful performance improvements over Alamouti’s conventional orthogonal design.

Flexible On-line Construction of IRA Codes for Packet Erasure Correction with Application to Aeronautical Communications

, 2011
In many applications erasure correcting codes are used to recover packet losses at high protocol stack layers. The objects (e.g. files) to be transmitted often have variable sizes, resulting in a variable number of packet to be encoded by the packet ...

Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization

EURASIP Journal on Wireless Communications and Networking, 2008
This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC) codes, especially in the context of noncoherent detection.

Low-density parity-check codes based on sparse binary sequences

Tongxin xuebao, 2005
A novel and simple construction of regular LDPC codes was proposed, which used sparse binary sequences, through studying construction methods of LDPC codes.

LDPC codes

, 2012
The aim of this thesis are problematics about LDPC codes. There are described metods to create parity check matrix, where are important structured metods using finite geometry: Euclidean geometry and projectice geometry.
