Concatenated LDPC-Polar Codes Decoding Through Belief Propagation

open access: yes, 2017
Owing to their capacity-achieving performance and low encoding and decoding complexity, polar codes have drawn much research interests recently. Successive cancellation decoding (SCD) and belief propagation decoding (BPD) are two common approaches for ...

Coded Cooperation for Multiway Relaying in Wireless Sensor Networks

open access: yesSensors, 2015
Wireless sensor networks have been considered as an enabling technology for constructing smart cities. One important feature of wireless sensor networks is that the sensor nodes collaborate in some manner for communications.

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

open access: yesEURASIP 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. Part I showed that a special class of DE-LDPC codes, product accumulate

Jointed LDPC codes design for half-duplex relay channels

open access: yesTongxin xuebao, 2013
In order to increase the coding gain of decode-and-forward half-duplex relay channel, a jointed LDPC coding structure and its corresponding optimization scheme was proposed. Novel structure made the subcodes of both source and relay nodes as parts of the

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution

open access: yesIEEE Access
This paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .
