Quasi-cyclic low-density parity-check (QC-LDPC) codes are the choice for data channels in the fifth generation (5G) new radio (NR). At the transmitter side, code bits from the QC-LDPC encoder are ...
What is an LDPC Code? •The percentage of 1’sin the parity check matrix for a LDPC code is low. •A regular LDPC code has the property that: –every code digit is contained in the same number of equations, –each equation contains the same number of code symbols. •An irregular LDPC code relaxes these conditions.
In this video Professor Rob Maunder discusses AccelerComm's LDPC codes.AccelerComm's LDPC channel code is a 3rd of the size of it's competition providing high performance low power 5G NR solutions in FPGA and ASIC.
QC-LDPC codes or their variants (such as accumulator-based codes ) that can be decoded using belief propagation (BP) methods are highly likely candidates for 5G sys- tems.
A new rate compatible structure for LDPC codes are employed for channel coding to fulfill the broad applications supported by the standard. Creonic’s 5G LDPC Decoder IP Core provides a perfect solution for this new LDPC structure with high level of flexibility while maintaining high throughput and low latency as required by the standard.
Turbo Codes and LDPC have served perfectly up to this point and will very likely do for a good while longer, but the requirements coming down the pipe for 5G are a lot more than just voice and video.
