IP Cores, Inc. (http://www.ipcores.com) announces additional Low Density Parity-check Code (LDPC) IP cores.

IP Cores, Inc., California, USA (http://www.ipcores.com) has announced new Low Density Parity-check Code (LDPC) designs.

“New LDPC cores extend our portfolio of error-correction encoders and decoders ,” said Dmitri Varsanofiev, CTO of IP Cores, Inc. “These products will help our customers to design state of the art error correction capabilities into their systems”.

Low Density Parity-check Codes

LDPC codes are frequently used in applications where efficient information transfer or storage is needed in the presence of data-corrupting noise. LDPC codes, also known as Gallager codes, were developed by Robert G. Gallager in 1960, but are getting very popular recently. The attractiveness of the LDPC code is helped by the absence of patent issues.
With the addition of the new cores, the IP Cores’ LDPC portfolio will include, among others, LDPC codecs for G.hn (ITU G.9960, G.9961), WiMAX (IEEE 802.16), WiFi (IEEE 802.11) and satellite communications (CCSDS C2). Cores are based on the layered belief propagation (offset min-sum) algorithm with input data in the quantized Log-Likelihood Ratios format (bit-LLRs).
