What is LDPC (low density parity check)?

LDPC was created by Robert G. Gallager in 1960. It is reasonable for error correction in large block sizes sent by means of noisy channels. It is a strategy for communicating a message over a noisy transmission channel. An LDPC is built utilizing a sparse Tanner graph. LDPC codes are discovering expanding use in applications requiring exceptionally effective data sent over bandwidth-constrained in the presence of corrupting noise.
