LDPC Bit Flip Decoder Definition

This block creates a LDPC Bit Flip Decoder Definition variable.

The decoder requires knowledge of the matrix used to create (encode) the codewords.

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

Max iterations

Max iterations may be increased from 100 for possibly better performance, but significantly higher number of iterations may slow things down.

LDPC FEC matrix ID

In the LDPC FEC Matrix ID field, input the ID of either a:

1) LDPC Generator Matrix variable, or

2) LDPC Parity Check Matrix variable
