This is a soft-decision decoder that uses belief propagation (also known as message passing) that is described at:


Designed for a memoryless AWGN channel, it assumes a noise variance of the value specified for sigma.


For parallel execution of multiple instances of the block (more info is needed on this)
Dimension 1
For parallelism
Dimension 2
