Abstract
A method includes: constructing complementary low density parity check codewords by generating a first codeword having a first code rate; and partitioning the first codeword by assigning groups of bits of the first codeword to four quarter-partitions, wherein each of the quarter partitions includes bits in one half of one of four independently decodable semi-codewords each having a second code rate that is larger than the first code rate. Receivers that receive signals produced by the method are also disclosed.
