Block
Description
The LDPC Encoder block applies LDPC coding to a binary input message. LDPC codes are linear error control codes with sparse paritycheck matrices and long block lengths that can attain performance near the Shannon limit.
The input and output are discretetime signals. The ratio of the output sample time to the input sample time is K/N, where:
N is the length of the received signal and must be in the range (0, 2^{31}).
K is the length of the uncoded message and must be less than N.
