generate, by the LDPC encoder, a first codeword having a first portion of the plurality of information bits; and

generate, by the LDPC encoder, a second codeword having a second portion of the plurality of information bits.

12. The wireless communication device of claim 7 , wherein the one or more processors are configured to set, for the codeword, a number of parity bits according to the codeword length.

13. A non-transitory computer readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

determine a count of a plurality of information bits;

select a number of codewords as a function of the count;

assign portions of the plurality of information bits to each codeword of the number of codewords, the portions having a substantially equal number of information bits;

generate, by a low-density parity-check (LDPC) encoder of the wireless communication device, each codeword using the assigned portions of the plurality of information bits, the codeword having the codeword length; and

transmit the codeword to an LDPC decoder of another wireless communication device.

14. The non-transitory computer readable medium of claim 13 , wherein the instructions further cause one or more processors are configured to:

select a first codeword length responsive to the count being less than a first threshold;

select a second codeword length responsive to the count being greater than a second threshold; or

select a third codeword length responsive to the count being between the first threshold and the second threshold.
