Electronics Letters, 1999•IET… A semi-random approach to low density parity check code design is shown to achieve
essentially the same performance as an existing method, but with considerably reduced
complexity. … In this Letter, we report a modified approach to LDPC code design. We adopt
a semi-random technique, ie only part of H is generated randomly, and the remaining part is
deterministic. The new method can achieve essentially the same performance as the
standard LDPC encoding method with significantly reduced complexity. …
