Abstract: Low density parity check (LDPC) codes have stimulated a lot of interest in recent years due to their capacity approaching performance and availability of fast decoding algorithms. The ...

Abstract: We propose an efficient encoding algorithm and architecture for 2-D quasi-cyclic (QC) low-density parity-check (LDPC) codes. The encoding algorithm is ...

A new technique for efficient encoding of LDPC codes based on the known concept of Approximate Lower Triangulation (ALT) is introduced. The greedy permutation algorithm is presented to transform ...

This is the older and deprecated C version of the Labrador-LDPC library, which is now written in Rust and available here. This version is kept around for posterity, and because the C version is ...

Having a plan to illustrate all the 5G Physical procedures with diagrams and flow charts, here is the first part for PDSCH LDPC encoding. The picture below is an example of LDPC encoding process for ...

Quantum Key Distribution (QKD) systems will be fundamental in ensuring secure communications in future networks. However, due to device imperfections and the random nature of quantum physics itself, ...

For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...

Instead, tailoring the encoding approach ensures efficiency and precision. 🔍 Transforming Base Graphs The base graph matrix (u) is transformed into the parity check matrix (H) using a lifting factor ...

* This function create the codec instance for the LDPC from file codec. * @fn of_status_t of_ldpc_ff_create_codec_instance (of_ldpc_ff_cb_t** of_cb) * @brief create a ...

Our LDPC encoding and decoding IP for the 3GPP New Radio uplink and downlink data channel includes the entire processing chain, to provide quick and e ...
