Novel LDPC coding and decoding strategies: design.
Multiple formulations of the soft- decision decoding algorithm have been published based upon Thesus s foundational work on LDPC codes R. Conventional LDPC codes have a low decoding. 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.
A.Introduction Low-density parity-check (LDPC) codes are a class of linear block LDPC codes. Their main advantage is that they provide a high performance and linear time complex algorithms for decoding. LDPC codes were first introduced by Gallager in his PhD thesis in 1960. 2 Alma Bregaj.
The research thesis was done under the supervision of Prof. Ronny Roth in the Computer Science Department. Acknowledgements Many people helped me in various ways in my work on thi.

A binary low-density parity-check (LDPC) code is a linear block code that is defined by a sparse parity-check matrix H, that is H has a low density of 1’s. LDPC codes were originally presented by Gallager in his doctoral dissertation (9), but largely overlooked for the next 35 years. A notable exception was (29), in which Tanner introduced a graphical representation for LDPC codes, now known.
