A fully parallel decoder requires a large amount of hardware resources. Moreover, it hard-wires the entire parity matrix into hardware, and therefore can only support one particular LDPC code. This ...

An area efficient LDPC decoder hardware design for parallel layered decoding algorithm is proposed. Shift register chain is used to reduce the chip area. Puncturing technique is employed to produce ...

Our proposed LDPC decoder improves the tuning when the column operations are performed, accordingly it improves the message-passing efficiency within the limited number of iterations for decoding. We ...

The LDPC Decoder The LDPC decoder receives blocks of data, including corrupted bits due to noise, with five or six bits resolution of confidence information for each 0 or 1 bit received. Decoding a ...

The first LDPC decoder was reported in [2] in 2002 as a fully parallel multi-bit architecture. All of the nodes are directly implemented on the chip and connected by a large number of wires.

A specialized Graph Neural Network + Reinforcement Learning (GNN+RL) based decoder for quantum LDPC codes, with a primary focus on lifted and balanced product LDPC codes. ldpc_decoder/ ├── config/ # ...

The DVB-S2/S LDPC/BCH decoder a silicon proven IP extracted from production chips has an octal input interface and a single output interface. The data coming from the 8 demodulators are multiplexed ..

Technical Terms LDPC code: An error-correcting code with a sparse parity-check matrix that approaches Shannon’s capacity limit with efficient iterative decoding algorithms. GPU: A graphics ...

AccelerComm, the company specialising in optimisation and latency reduction IP, has announced they have developed a highly optimised LDPC software decoder in collaboration with Intel. The solution is ...
