Embodiment techniques map parity bits to sub-channels based on their row weights. The
row weight for a sub-channel may be viewed as the number of “ones” in the corresponding
row of the Kronecker matrix or as a power of 2 with the exponent (ie the hamming weight)
being the number of “ones” in the binary representation of the sub-channel index (further
described below). In one embodiment, candidate sub-channels that have certain row weight
values are reserved for parity bit (s). Thereafter, K information bits may be mapped to the K …

Embodiment techniques map parity bits to sub-channels based on their row weights. In one
example, an embodiment technique includes allocating, from a set of sub-channels, one or
more sub-channels for one or more parity bits based on row weights for sub-channels in a
subset of sub-channels within the set of sub-channels, mapping information bits to
remaining sub-channels in the set of sub-channels based on a reliability of the remaining
sub-channels without mapping any of the information bits to the one or more sub-channels …
