Low-Power Non-Binary LDPC Decoder Design via Adaptive Message Length Control Exploiting Domain-Specific InformationWith the enhanced performance and convergence speed than their binary counterparts, NB-LDPC codes have been considered for emerging wireless communication and storage applications. However, one ...
[Y,actualnumiter,finalparitychecks] = ldpcDecode(llr,decodercfg,maxnumiter) decodes the input log-likelihood ratio (LLR), llr, using the LDPC matrix specified by the input ldpcDecoderConfig configuration object, decodercfg. A positive LLR indicates that the corresponding bit is more likely a ...
While binary LDPC codes have shown great performance, nonbinary LDPC codes have empirically shown even better performance, especially for small codeword lengths. A configurable output synchronous FIFO is used to store the output for the next block. 查看Non-binary LDPC Decoder 详细介绍: 查看Non-...
Layered Message Passing AlgorithmDynamic SchedulingRecently, LDPC plays a vital role in error floor performance near to Shannon limit. LDPC mainly suits, when length of the codeword is large, over the finite field. This paper presents parity check matrix of non-binary LDPC encoded innovatively ...
-Check) and BCH codes. LDPC codes, invented by Gallager in his seminal doctoral thesis in 1960, can achieve extremely low error rates near channel capacity by using a low-complexity iterative decoding algorithm. The outer BCH codes are used to correct sporadic errors made by the LDPC decoder....
If decoding fails, the message portion of the decoder input is returned unchanged as the decoder output. The sample times of all input and output signals are equal. This icon shows optional ports. Examples DVB-S.2 Link, Including LDPC Coding in Simulink ...
For example, we implement an LDPC code designed for a binary symmetric channel (BSC). This design is not tuned to the fingerprint channel model. One possible improvement is to refine the design of the LDPC to match that channel. In general, however, while the “fingerprint channel” is a ...
This paper presents approaches to develop efficient network for non-binary quasi-cyclic LDPC (QC-LDPC) decoders. By exploiting the intrinsic shifting and symmetry properties of the check matrices, significant reduction of memory size and routing complexi
