Low-complexity decoding of LDPC codes
Nishit Pandya, B. Honary · Electronics Letters · 2007
The offset BP-based algorithm is a reduced-complexity derivative of the belief-propagation algorithm for decoding of low-density parity-check codes. It uses a constant offset term to simplify decoding, but at the cost of performance. A method to obtain a ‘variable’ offset parameter is presented here, to improve the performance of the algorithm.
