LDPC Decoder Definition

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.

Parameters

 * Parallelism
 * For parallel execution of multiple instances of the block (more info is needed on this)


 * Dimension 1
 * For parallelism


 * Dimension 2
 * For parallelism


 * AList file
 * Name of an alist file to use.


 * Sigma
 * Noise variance of the channel


 * Max iterations
 * Maximum number of iteration for the message passing algorithm
