Abstract :
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.
