LDPC error correcting codes

Used in IEEE 802.11n-2009 (Wi-Fi), 10GB Ethernet and 5G, ldpc codes are starting to replace Turbo Codes in systems with a large code rate. In this work, we study ldpc in two channels: the bec and the bmc. To quantify the performance of the codes, we will compute their BER (Bit Error Rate) P_e and BLER (Block Error Rate) P_b.

Implementation

The LDPC decoding and code generation were implemented in Rust. All the code is thoroughly documented and can be accessed at this address: https://github.com/grodino/ldpc. The commands associated to each figure in the report are described in the readme.md file.
