Parity-Check Matrix Partitioning for Efficient Layered Decoding of QC-LDPC Codes

Efficient iterative decoding algorithms for turbo and low-density parity-check (LDPC) codes

Scheduling parity checks for increased throughput in early-termination layered decoding of QC-LDPC codes on a stream processor

A stream processor is a power-efficient, high-level-language programmable option for embedded applications that are computation intensive and admit high levels of data parallelism. Many signal-processing algorithms for communications are well matched to stream-processor architectures, including partially parallel implementations of layered decoding algorithms such as the turbo-decoding message-...

New Iterative Decoding Algorithms for Low-Density Parity-Check (LDPC) Codes

Low-Density Parity-Check (LDPC) codes have gained lots of popularity due to their capacity achieving/approaching property. This work studies the iterative decoding also known as message-passing algorithms applied to LDPC codes. Belief propagation (BP) algorithm and its approximations, most notably min-sum (MS), are popular iterative decoding algorithms used for LDPC and turbo codes. The thesis ...

Efficient Decoding Techniques for LDPC Codes

Efficient decoding techniques for LDPC codes are in demand, since these codes are included in many standards nowadays. Although the theoretical performance of LDPC codes is impressive, their practical implementation leads to problems like numerical inaccuracy, limited memory resources, etc. We investigate methods that are suited to reduce the decoding complexity while still keeping the loss in ...

Jointly Iterative Decoding of Low-Density Parity Check codes (LDPC) coded Continues Phase Modulation (CPM)

This paper investigates the performance of a LowDensity Parity Check codes (LDPC)-coded system transmitted over A WGN channels using octal partial response Continuous Phase Modulation (CPM). The system provides an attractive option for spectral efficient communications systems. The CPM modulator can be decomposed into a ring continuous-phase encoder (CPE) followed by a memoryless modulator (MM)...
