Low-Density Parity-Check Codes for Satellite Communication Links
Quick fact
LDPC codes were invented in 1963 by Robert Gallager but were largely ignored until the late 1990s because their decoding was computationally too heavy for the time.
Why this is interesting
You know that moment when a live satellite video freezes or stutters? It's because the signal is corrupted by noise and interference. But how do we fix this without retransmitting everything?
