Parallel layered LDPC decodingThis paper presents a memory efficient architecture of layered decoder for the dual-rate LDPC codes in the China Multimedia Mobile Broadcasting (CMMB) system. An efficient scheme for reducing the memory block number is proposed to increase the memory usage efficiency, so...
Although illustrated as a single component that can perform encoding and decoding of data, the error corrector 113 can be provided as separate components. In some embodiments, the error corrector 113 is operative to encode data according to a Low-density parity-check (LDPC) code. The error ...

The Euclidean projection involved in the decoding of low-density parity-check (LDPC) codes with the alternating direction method of multipliers (ADMM) can be simplified by jointly using uniform quantization and look-up tables (LUTs). However, the memory requirement for the original LUT-based ADMM...
802.16-2009, increases in decoding speed of up to 1.52X per iteration are achieved for overlapped message passing algorithm-based architecture, along with considerable reductions in the number of memory-read accesses. Using a 0.13-渭m CMOS process, a QC-LDPC decoder with multi-code rates is ...
memory error correction code has been implemented using pipelined cyclic corrector where majority logic gate determined the error .LDPC soft error decoding is also implemented for the same memory error detection and correction comparison of the results are done .as the majority gate can detect only ...
This paper presents a memory efficient partially parallel decoder architecture suited for high rate quasi-cyclic low-density parity-check (QC-LDPC) codes using (modified) min-sum algorithm for decoding. In general, over 30% of memory can be saved over conventional partially parallel decoder ...
This paper presents an error detection and correction method for Euclidean geometry Low density parity check (EG-LDPC) codes with majority logic decoding. Here the application is mainly focused on memories, since MLDD is used here due to its capability of correcting large errors. Even though they...
