Due to huge computational requirements, powerful Low-Density Parity-Check (LDPC) error correcting codes, discovered in the early 1960s, have only recently been adopted by emerging communication standards. LDPC decoders are supported VLSI technology, which delivers good parallel power with excellent throughputs, but at expense of significant costs.
