LDPC Encoder Definition (via Generator)

A standard encoder class. This method is discussed in many textbooks; one is: Turbo Coding for Satellite and Wireless Communications by Soleymani, Gao, and Vilaipornsawai.

Given a generator matrix in systematic form, G = [I|P], where I is the identity matrix and P is the parity submatrix, the information word s is encoded into a codeword x via:

x = G'*s

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

LDPC generator matrix

The ldpc_G_matrix object to use for encoding.
