Robert Gallagher first proposed these codes. At the time, their. Low- Density Parity- Check Codes: Thesis, on low- density parity- check codes, was published by the MIT Press as a monograph in LDPC codes were invented by Robert Gallagher [ 1] [ 2] in the early s; in his doctoral thesis he has proposed a pseudo- random method which generated good. You can certainly find the sum product algorithm there.

Construction and Implementation by. Conventional LDPC codes have a low decoding. Low Density Parity Check Codes. Conventional LDPC codes have a low decoding complexity but may tehsis high encoding complexity. Lets look at an example for a low- density parity- check. Compare it to a similar iterative algorithm known as Gallagher Hard Deci. Gallager, and Pearl’ s iterative belief.

He proposed the coding scheme and a decoding scheme and claimed that these can approach the Shannon limit. Gallager’ s Sc. Thesis in and were then rediscovered by, among others, MacKay and Neal in Since their lcpc discovery LDPC codes have become very popular.

Gallagher, at that time practical implementation was impossible and it passed out of mind. This thesis is about construction of LDPC codes and their hardware implementation.
