Low Density Parity Check Codes

Conventional LDPC codes have a low decoding complexity but may have high encoding complexity. The purpose of lxpc thesis, therefore, is to set forth an evaluation of the concept of neural network design related to Low- Density Parity- Check LDPC code structures and algorithmic aspects.
