This paper presents a novel auto-encoder based end-to-end channel encoding and decoding. It integrates deep reinforcement learning (DRL) and graph neural networks (GNN) in code design by modeling the ...

The encoder block diagram shows that one input to each multiplier is a constant field element, which is a coefficient of the polynomial g (X). For a particular block, you input the information ...

The IPrium-LDPC-CCSDS-AR4JA-Encoder-Decoder IP Core implements Low Density Parity Check (LDPC) forward error correction algorithm for AR4JA CCSDS 131.

The CCSDS LDPC codes are used by NASA and other space agencies in modern transceivers. These codes were designed to be easy to decode by ensuring the parity check matrix is sparse. However, the ...

Thanks for opensourcing these amazing models. I was probing into the intermediate tensors and found that they have extreme values even in the presence of norm layers and gating, especially in later ...

The IPrium-LDPC-802.11-WIFI-Encoder-Decoder IP Core implements Low Density Parity Check (LDPC) forward error correction algorithm for IEEE 802.11n/ac/ ...
