LDPC Rate Display values are 0.4 (2/5), 0.6, (3/5) or 0.8 (4/5). The LDPC Rate
provides three rates of forward error correction. The decimal, or fraction,
gives the relative efficiency of the forward error correction by dividing
the information bits by the total block length. For example, block length
= 7488 bits, information bits = 3008, therefore: 3008/7488 = 0.4 or 2/5.
This indicates that there are two information bits for every five output
bits.
Time Interleaver Display values are 240 or 720symbols. This is a data convolutional
interleaver. The data is interleaved to a depth of 240 or 720 symbols.
