Ldpc Matlab Code

A low-density parity-check (LDPC) code is a linear error correcting code, a method of transmitting a message over a noisy transmission channel.  An LDPC is constructed using a sparse bipartite graph. LDPC codes are capacity-approaching codes, which means that practical constructions exist that allow the noise threshold to be set very close (or even arbitrarily close on the BEC) to the theoretical maximum (the Shannon limit) for a symmetric memoryless channel. The noise threshold defines an upper bound for the channel noise, up to which the probability of lost information can be made as small as desired. Using iterative belief propagation techniques, LDPC codes can be decoded in time linear to their block length.The following matlab project contains the source code and matlab examples used for ldpc.

The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
