Classical low-density parity check (LDPC) codes have a well-established design theory: by choosing how many checks connect to each bit, retaining appropriate randomness, and avoiding short loops, ...
For communication designers, especially those in the networking and wireless field, the Shannon limit can be seen as the Holy Grail. And, since being first defined in ...

The LDPC code breakthrough, why small random parity sets outsmarted every structured approach
When transmitting data across noisy channels, the quest for perfect reliability seemed to demand ever-more complex structure — until Robert Gallager's 1960 insight showed that small, randomly assigned ...
