GALLAGHER THESIS LDPC

Conventional LDPC codes have a low decoding complexity but may have high encoding complexity. Since their re- discovery LDPC codes have become very popular. Soon after their invention, they were largely forgotten, and reinvented several times for the next 30 years. Omitted from the thesis.

This thesis is about construction of LDPC codes and their hardware implementation.

I wish to highlight the. You can certainly find the sum product algorithm there. Actually, you can sort of find it in Gallagher’ s thesis. LDPC codes were invented by Robert Gallagher [ 1] [ 2] in the early s; in his doctoral thesis he has agllagher a pseudo- random method which generated good.

Soon after their invention, they were largely forgotten, and reinvented several times for the next 30 years. This thesis is about construction of LDPC codes and their hardware implementation.
